Admin doesn't have access !

Hi guys !

I have an issue with the plugin.
When I want to edit an operation, the plugin said to me that I don’t have enough permission to access this area…..

I don’t understand why ? I setuped this operation and I am the only one user on my wordpress installation.

Can I get some help ?

This are the screenshots that I get http://imgur.com/a/E3qda
