Internal Server Error

Hello! I am using your plugin for a client who needs access to just the “Posts” portion of the WP Admin backend. I created a username for him, set his role as “Contributor”. I used your plugin to specify access to all of the Post areas of the backend.

However, when my client tries to create a new post, he keeps getting an Internal Server Error. He can login, see the posts already created, but whenever he tries to interact with them, bang, up comes the server error.

Not sure if you have had issues with this before, but any assistance would be appreciated. ??
