I am using Atahualpa 3.6.4 and have encountered a strange error that I can't figure out. This probably doesn't have anything to with Atahualpa, it's most likely a general WP issue, but I need help and this forum has sometimes been the perfect place to go for assistance.
Recently I started getting an error message whenever I added a page to my navigation menu. Even though I got an error message, the menu change actually worked OK, so I could ignore the message and move along. However, tonight I can't make ANY changes to the menu structure. I get this error message consistently, and I'm unable to add any new pages to the menu:
Error 500 - Internal server error
An internal server error has occured!
Please try again later.
I installed a plugin to monitor memory usage, and it says I'm using 21 mb and have 64 mb available, so I don't think that's the problem. I tried disabling all plugins, and the same error persisted. I am running the latest WP 3.1.2 with Atahualpa 3.6.4.
I would be most grateful if anyone had any advice for me on how to fix this problem.
