Common vqmod issues

I am getting far too many general support queries relating to installing vqmod, so thought I would try to help by referencing the common issues I have experienced.

Vqmod wiki on how to install it correctly.

Upgrade to the latest vqmod, this will help we debugging and number of fixes/performance improvements. See full list of changes.

Common vqmod things to check:

• Have you deleted the required file: vqmod/xml/vqmod_opencart.xml? This is required for opencart.
• Have both index.php and admin/index.php been modified by vqmod? If you have changed the directory of the admin, you will need to make the changes manually - see wiki.
• Does vqmod have the correct write permissions - see wiki.
  You can check if its working correctly by emptying the vqcache directory and refresh your website, check the vqcache again to check the files have been re-generated.
  Also old versions of vqmod used to read from the cache for 60 seconds if you dont see your changed instantly this check useCache = false.
• Moving vqmod .xml files into a sub-folder will not uninstall them, they need to be either moved completely out of the vqmod/xml folder or rename *.xml to *.xml_

Check your error log, either vqmod/vqmod.log or vqmod/log. If vqmod is functioning correctly it will write to the error log exactly what is wrong.

Common Vqmod Errors

• Error: DOM UNABLE TO LOAD, is usually related to character encoding.
  1. Validate the XML file here: http://www.xmlvalidation.com/
  2. Add <?xml version="1.0" encoding="UTF-8"?> to the top of XML file
  3. Use a application like Notepad++ which can ensure the file is saved in Encoding UTF-8
  4. Ensure any non-standard characters (á, é, etc) are wrapped in CDATA
  5. Re-upload the vqmod XML files, this may of been corrupted when uploading

Excellent post! You may want to change this bit though:

Moving vqmod .xml files into a sub-folder will not uninstall them

This will effectively keep them from running as VQMod only looks for scripts in /vqmod/xml/.

Cheers, I have just tested with latest vqmod your correct. Although I was 100% sure this was the issue on an old version of vqmod.

I'm fairly sure it was never in VQMod (it's not in v1.2.3 which is the earliest I have). There's not much point in wasting resources on recursive look-ups.

Also for anyone interested VQMod Manager 2.0 Beta does a number of checks to make sure VQMod is installed correctly.

Very nice and I recommend it to everybody.

Just had a look through your code for v2 and really impressed. I can imagine how much harder its been writing it to work for different versions of vqmod, especially the changes to the logging system and caching.

The only thing which I think its missing is the ability to filter/search the error messages more easily.

Few ideas how this could work:
1. Filter by extension developer.
2. Filter by types of errors. Not found, etc.
3. Giving a grade to the different errors, marking anything which is critical. You could even add some suggestion on how it could be fixed.
4. Grouped repeated errors.
5. Display a report/break down of any other vqmod files which have edited the same file. E.g there is a conflict between 2 extensions. It would be really useful to know which over extension is editing the same file.
6. Delete a single error (or group of same errors). Lets say I have the job of fixing the vqmod errors which have accumulated over a few weeks(big file and lots of duplicates). I dont want to clear the log encase I miss something, instead I would like to delete the error as I fix them one at a time.

Truth is I wrote a log parser on two different occasions then gave up. Things kept getting changed around too much.

In the vqmod manager does it check the version?

E.g it would check the current installed version, then highlight any installed vqmods which have or less than.

Can't unfortunately. It's a private variable.
