HTTP ERROR 500 created by plugin

Hi

I was getting a HTTP ERROR 500 when trying to delete a user. Then I found out that anyone trying to become a user of my page, was not able to see protected content even though their membership allows them to see the content. So I unplugged plugins one by one and found the Hustle plugin to be the main source of the problem, cause with Hustle unplugged I was then able to delete users, and new created users were able to see protected content.

Best regards
Peter
