I was set up a menu item for the maps and when I went into a location and tried to change the icon that it used as soon as I saved I got this error.

Not Acceptable

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

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

I tried to refresh the page and no go, I tried a different browser and the site worked but as soon as I tried to change the icon I got the same error. What is weird is that it only affects that domain and I cannot even access cPanel without getting an error.

What is going on? Any ideas??
