Having an issue with the editor where randomly I'll get a "Access Denied" message when trying to preform some sort of action. One example is create new custom attributes. I'll go to save it and then on submission it'll kick me to a page that says "Page Forbidden". Hard refresh a couple times and the submission goes through.

I am logged in as an Administrator, cookies are enabled, and I set it to keep me logged in for 2 weeks. This happens no matter the browser I use.

Thoughts?
