Open cart product page goes blank upon theme uploa

问题:

Here's the scenario: Fresh install of Open Cart. Fresh install of vQmod. Everything is working fine. But when I upload certain theme - purchased and licensed - the site has an issue. The home page is working, but the product page goes blank.

I have tried all possible combinations of OpenCart and vQmod versions (except for 2.0 for OC because the theme doesn't support it yet). I am out of ideas.

Edit: After showing all errors as adviced I finally saw the reason : "oc_product_tab' doesn't exist"

I found a solution. It turned out that the "Extra Product Tabs Opencart Extension" is missing. This is a standart free plugin that comes with template theme but it wasn't configured. It turnes out that the theme works with it.

Go to system>users>user groups and select all for both access and modify. Save. Than go to Catalog menu and click on Extra product tabs. Click Insert and add the module. That’s it. It’s a standard opencart module which is free for use.
