OpenCart Community

Hi there,

I have the 1.5.1.3 install of OpenCart. On the category page I have some products from the sub-cats and the buttons:

Add to Cart
Wishlist
Compare

At first they appear inactive but when I examine them in my Firebug they are giving the following error when clicked:

Notice: Error: Could not load library json! in /home/gadgetdr/public_html/system/engine/loader.php on line 23

From memory this was a fresh install of 1.5.1.3 so there should be no upgrade bugs.

Any help would be great. I am running Shoppica theme but I don't think it is related to the theme (could be wrong)

many thanks

reupload you might be missing a few files.

The problem is likely due to a 3rd party mod trying to call the old 1.5.1 method for loading json as library.
In 1.5.1.3 it was moved to the helpers area and no longer gets loaded as a library. That 3rd party addon will need to be updated

Thanks guys, thats awesome, will investigate those points. Qphoria that sounds like it's prob the case, as when i run the store on the default theme it works fine. Cheers again, Matt

Hi,
I'm newbie opencart user and I have a problem with mr json...
In log I find this error:

2011-12-28 17:18:10 - PHP Notice: Error: Could not load library json! in /store/vqmod/vqcache/vq2-system_engine_loader.php on line 24

And the reviews don't work...
I tried to disable all VQMod script, but nothing happens.
I tried to reinstall the theme (http://www.12leaves.com/store/crista-op ... plate.html)
but nothing happens...
Can you help me to find the problem?

The error isn't with vQmod.. its with another addon is not 1.5.1.3 compatible.
In 1.5.1.3, the json model was changed to a helper... so really the fix is to remove any reference to trying to load json as a model... and alter the function.

So find out which custom mod is causing it as it is not likely a vQmod script but an extension.. possibly payment. And check with the author for an update.

Thank you, but is there a method to find the wrong extension?
Excuse me for the question but I'm not an expert.
I thought that was vQmod that caused problem because the file indicted was vq2-system_engine_loader.php
Have I to look a particular call in files?

Uninstall your mods one by one (including the theme), take your install back to standard open cart, until it works. That'll tell you what the offending mod is.

Just to update you on the original post. Qphoria's post about the 3rd party mod trying to call the old 1.5.1 method for loading json as library. I updated the 3rd party mod and it jumped into life. Thanks for the help.

Hi everyone,

i installed 1.5.4.1 and a 3rd party modul for payment. everything is ok. but someone come to check out, begins the problem. My modul also call the old method for loading json as library. So how can i fix it? how can i change the call method or folder name etc?

Sorry for bad eng. and i'm not soo good at opencart
