If you see an error message that says "Warning! You do not have permission", you can fix it with the following steps:
- In your OpenCart admin go to System > Users > User Groups
- Click Edit for the User Group that your user is a member of (usually Top Administrator)
- Find the module or tool that you wish to access - eg tool/total_import for the Total Import PRO - and tick the box next to it in both lists.
The Permissions page is OpenCart's way of restricting access to admin pages to different users. This way you can hide your financial reports, for example, from your data entry team. When a new module or tool is installed it has no permissions for any User Groups by default, so the above steps are necessary before first use.
Here is a video outlining the problem, and how to resolve it.
