It has to be your server, files, permissions & et cetera. Back everything up if you haven't already and just reinstall it the server. I searched your issue and all I saw was the plugins not properly being named .dll or .so in the server.cfg. Look through your server.cfg and see if there's the slightest error in the lines.

Look at this post. There might be a fix in 1 of the 5 pages.
