Question

I am an administrator, and I have installed an extension of News Letter from:

http://www.opencart.com/index.php?route=extension/extension/info&extension_id=12825

When I attempt to use this, it returns the error below:

error: You do not have permission to access this page, please refer to your system administrator.

Answer 1

1. Login to admin, go to System > User Group.
2. Edit your admin usergroup (probably Top Administrator group).
3. Add permission to your new extension modules (both Access Permission and Modify Permission).

That's all.

Have a nice day :) !!
