You do not have sufficient permissions to access this page.

Hi there

When I try and view any of tabs of wp
it gives the following error

You do not have sufficient permissions to access this page.

Please advise. Urgent matter.
Site still works.
Other plugins work.
Only plugin that does not work is better-wp-security

Cheers
