Need your kind help in identifying this problem that i encountered recently in opencart. what may seems to be the problem that causes this error.
2017-11-17 2:48:46 - PHP Notice: Undefined variable: categories_info in /home//domains//public_html/vqmod/vqcache/vq2-system_storage0n9nb4ewxm1o_modification_catalog_controller_common_header.php on line 115
Thanks in advance
Because the error message contains your vqcache folder, the problem is probably caused by one of your extensions. In this case the first step is to identify which extension by disabling them one by one and seeing if the error still occurs.
Once you've identified which extension is causing the problem, the best course of action is usually to contact the extension developer via the OpenCart Contact Us page: https://www.opencart.com/index.php?route=support/contact
