Our Support team is ready to present a new tutorial that will show you how to deal with Access Denied issue in Magento admin panel.
The error might appear after creating a new user and assigning a wrong role to it:
Try to log out of your admin panel and log in again. In case this does not solve the problem, there are 2 ways of resolving the issue:
Log out, log in with the other user login information.
You will need to change the first user role. Navigate to System > Permissions > Users. Open the first user and change the user role:
Alternatively, you can reset the admin privileges:
This can be done through the Magento admin area System > Permissions > Roles . Select the Role.
Click on the Role Resources option from the left menu and make sure that Resource Access is set to All:
Click on the Save Role button and the privileges will be reset.
