406 Not Acceptable

[diyautoftw]

Hello everyone,
I have a user who occasionally gets odd errors when posting forum topics. The error says
"Not Acceptable

An appropriate representation of the requested resource /showthread.php could not be found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."

He's the only one that has gotten this error so far, but I want to figure out the issue before anyone else runs into it. Any ideas or suggestions helps! Thanks in advance!

Check with your host and see if its a mod_security related issue. I'm not exactly sure how it's handled, but I've heard of 406 happening with mod_security enabled. Might help to give them the users IP address.
