Greetings,
I have an issue when trying to edit my menu. When I make changes and attempt to save them, I get this server error and have to clear my cache for the website to be available again.

"Not Acceptable

An appropriate representation of the requested resource /~gdcadmin/DevSite2/ 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."

I've never had this issue before so I'm fairly sure this is must be the module. md_megamenu-7.x-1.12.zip (214.61 KB).

Please, this is time sensitive as I'm trying to build a site for a client. Thank you.
