Do you get annoyed when this error appears?

I am currently operating OC 1.5.6.1.

Often I discovered this is caused by bugged extension or simply not updated by the creator, etc. - paid or not paid.
I do not blame them, but I am pleased this works.
When that happens and also for other reasons, you get the error:

VQMod does not appear to be properly generating vqcache files!

Well, I found [at least on OC 1.5.6.1] that if you 'rename' the file mods.cache within the YourWebsite/VQmod folder and refresh the VQMod page in administration, it would work fine.

If it has occurred because of a recent Installed Extension and cannot read the VQMod page to unistall or delete extension, just go to YourWebsite/VQmod/XML and add a '_' [underscore = _ without the ' ' ] and OC takes that as uninstalled - I do this to 'keep' the file.

Then if the VQMod still gives the error, do the mod.cache thing above and it OC should recreate it and it should re-appear.

This I found the fastest way of getting back to business in minutes, instead of loosing yourself in PHP files!

For some this is obvious, it was not to me - also the 'delete all vqmod-cache files' recommended sometimes 'creates' the ERROR above, instead of fixing it and I believe it is because of some 'coding' problems within OC and VQMod interacting - not 'just' an extension.
I am no coder, so it is an opinion of a 'hard-worker' in IT.

So, this is not a fix, but just a way to get back to a working ADMIN without further waste of time.

I love OC!

Hi, after remove the vcache I have same problem.
When you said "rename" mdos.cache, what is the new name you used?

Thanks

Hi
The re-name it was meant as explained just to 'keep' it and NOT to let OC find it and it would re-create it.

The re-naming in general is always meant as 'keep' the file ... while doing something.

Having said that, there are many different situations.

I also mentioned:

If it has occurred because of a recent Installed Extension and cannot read the VQMod page to unistall or delete extension, just go to YourWebsite/VQmod/XML and add a '_' [underscore = _ without the ' ' ] and OC takes that as uninstalled - I do this to 'keep' the file.

Bear in mind, this is NOT an infallible way!
Like any 'workarounds' it usually works and it may not work for you.

I also found that the majority of people that are asking for this fault, actually the same questions were answered on other threads.

I am no coder, but I have some experience and this post was only to 'try' and help others.

The Cache problem is simply 'one' way of the VQMod to express: 'I am broken - fix me!'
This means it could be caused by many things.

The most common I see is Extensions not working well on certain OC versions and if you did install a Extension prior to this problem, do as said above to exclude it.

I also seen that we should not leave [ in the System/USers/Users Group ] all ticked/checked - in fact one of those I leave un-checked is 'settings' - unless it is needed.

Try the above and if you do not remember which extension may be the last one/s, just re-order 'by date' the XML files within VQMode/XML folder and add a _ [underscore] at the of file - i.e. re-name it by 'only' adding an _

As mentioned for OC this means the extension is disabled.

It may work.

PST I am not constantly connected to OC forums, as I am busy on other stuff and I might take ages before replying - sorry.

good Morning

My advise is for Dummies like me, all others know about, I am aware of that...

just to round up this thread for those who don't know, the OpenShop Versions v1.6/v1.7 of OpenCart have a very nice VQMOD Administration, called TWEAKS, in the Admin Section of the Software. One can enable/disable all VQMOD's installed, if required, the on/off Mod-Switch automatically add's a >_< to the .xml ending to look like >.xml_<, if a Mod is disabled. One can troubeshoot Mods, check, if they have possibly collisions with other Mods, and so on....

Image

------

Or then, use the popular >VQMOD-Manager<, I had no problem using ith with my OS/OC 1.5.6.1. based Versions.

Image

VQMOD Manager Option also has a >Settings and Maintenance Tab<, where the Cach Sections can be flushed and emptied at once or selectively.


http://www.opencart.com/index.php?route ... OD_Manager

And here my little fix to add an Icon into the Admin Section for the VQMOD-Manager as shown above in Image No.1:

Image

VQMOD's have not to be uploaded or deleted manually by using an FTP Client, they can be fully handled from the Server by VQMOD Manager as well.

------

Just be aware, that certain VQMOD's automatically create additional >DB-Table Entries< just by having them uploaded and the Software working. If possible Errors exist due to such DB-Manpulations, it is possibly required to remove Modifications, created by a VQMOD, manually by PHPAdmin or so. OpenShop also has a nice PHP-Admin built into the Admin Section to handle such tasks.

Hi
Thank you for this.

I had a 'quick' look a few days ago at OpenShop, but did not have the time yet to see all its features.

Interesting to know VQMod - as it seems to be an annoying problems that does not want to go away in 'any' vesrion of OpenCart.

I do know once you installed it on opencart, you can switch it on and off without problems [or so I read!].

But what if we want to, UN-install it completely?
i.e. will it UN-install without 'messing' up the OpenCart configuration on 1.5.6.1 and database [if it created tables]?

I am asking this because, I already wasted 2 days [twice] to fix the d**n OC messing up user_group/vqmod etc. and that thankfully made me learn how it generally works and now I can 'almost' easily get out of the usual annoying CACHE problem.

I just do not wish to get into that messy 2 days again if I install/UN-install OpenShop!

Also, you do mention 'VQMOD-Manager' ... the big problem is not getting into the vqmod - the button is certainly useful. The main problem is not having that button [which is nice to have - of course], but it is to 'avoid' altogether the Cache problem and 'not' be able to reach the VQMod Manager Page to actually switch on/off extensions - hence the need to rename-add _ to end of file name 'manually'.
Also, sometimes VQMod locks itself [always with the cache ...] if it does not like the setting 'serialised' into table user_groups, hence [again] having a backup of it in case you get stuck.

I did not waste time to check exactly which php files mess thins up [this time], but 'also' when some of the php files have been modified by a extension or 'manually', VQMod gets upset and you get 'again' the above problem with the table user_group and still does not work until you replace some of the php files and in my view that happens because we need an extension to 'protect' OC from these problems - i.e protecting a series of file that the developers know to be 'necessarily kept safe' or all hell breaks!

I really wish to try OpenShop as soon as I have read around what others say - mainly which problems they may have had [not of their doing], so I will know if I can fix them myself, in case they happen - like I did/do with OC VQMod when that happens.

Having said that, I bow to the developer of OC for helping thousands of tiny and small businesses [the people] that cannot afford it and can now be beside the large businesses [large too I noticed they disguise it - do not remember who now!]


Thanks

@openact: The vqmod option is, at least from the first impression, a great thing to have, because just about anyone can try new options without the need to modify existing Source Files. But because there is practically no limit to what some can do -there is no BOSS to 'regulate' Standards- as a consequence of this, hundreds of vqmods try to 'operate' and function in a kind of OPEN environment.

vqmod's call specific Routines, Lines, whatever, in order to -Add, Replace, whatever-, -Before, Instead of, After, whatever- (to) a specific piece of Text Line, wich is existing in JUST exactly the way it is written on the File to be 'temporarely altered' before it's content is to be sent to Output.

This is VERY SIMPLE STUFF. Basically. And as long as nobody else EVER Makes any modification on that specific Line, or even add's another exactly SIMILAR Piece of Line anywhere else, possibly even above the one mentioned, on that File, And as long Nobody ever creates another VQMOD wich is able to modify or change the Temporary Stored Content of what will be finally sent to the Visitor as Page Content, before the VQMOD is even Part of the Game, because the Server will call it AFTER another VQMOD has already modified the Server TEMP File to it's latest version and so the later VQMOD will not find it's OWN Line anymore and will therefore possibly not longer function.

Or worse, another VQMOD has been poorly written and misses b.Ex. -?>- -</div>- or other important things...

I have written a posting regarding this here:

http://forum.opencart.com/viewtopic.php ... 40#p488347

Personally, I would rather upload 4 to 6 'modified' Standard-Files into present Subdirectories, using a simple install/backup Script with the Ability to add a _ or whatever to the existing File Name Ending before uploading the new modified one. But doing it this way, anybody could just download the best stuff and soon, we would have millions of new Stores all over the Place.

OpenCart has a lot of good stuff in it, but during the years, it grew into a relatively 'fat' and slow Baby. I would not like to try to run the Software on a Pentium2 Server from a decade ago, it would probably require multiple seconds to create a Product Page. Locally, not past the Web! An unbelievable Situation for a Guy used to Auction Product Pages loaded within 10's of a second, or sorting /displaying 10'000 Item-Lists just like that. As I wrote, I know, there was little Glamour, not much moving Stuff on the Page, and certainly no Facebook/Youtube-Mod's. Other than that, I really do not see so much Difference, both Sources have, by Nature of the OS, Dis- and Advantages.

So much to VQMOD's, the way I look ad it. I don't want to raise a dispute about it either, it's everyone's own choice. I just felt to tell you what I do here with OS. I think I can make it to be a very efficient tool to meet the Expectations of the somehow typical swiss/german Consumer Group. (I mean the german-speaking Swiss only...)

But this does not belong here.. ;)
rgds,

Ernie
