Trying to add UDT returns "Not Acceptable"

[mrmut]

Hello all!

I have running CMSMS 1.6.8 installation, and I've tried adding a bit of PHP to the site but the server returns:

Not Acceptable

An appropriate representation of the requested resource /cmsms/admin/adduserplugin.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.

I don't have any plugins that might interfere, and as I have this version working on many other sites, I don't get this. I've reuploaded the "problematic" file from the error, but I still get the same problem.


Thanks a lot for any help!!

I have solved it: the problem was with the security rules of the host provider.

can you share: which rules exactly?

I have had this before on one of my hosts. In an attempt to prevent hackers from POSTing PHP code in an attempt to hack your site, they reject anything POSTed that looks like PHP. In my former hosts case, they had automatically put my IP address on a ban list, and I had to file a ticket to be removed from it. There was a setting in CPanel somewhere that I had to turn off.

there was nothing i could do.. problem was solved by my server administrator, he changed some mod_security settings and now everything runs just fine..
