I have a wierd problem with my 2.4.0 install. After I moved servers my file manager navigation/pagination (1,2,3) and the "thumbnail" option in the dropdown selection stopped working.
Clicking a navigation item just send the user to the site homepage. The URL it's trying to load is this (on hover): http://domain.com/system/C=content_publish&M=filemanager_actions&action=directory_contents&tbl_offset=15
I've tried re-uploing the entire /themes/ folder but that didn't do it. Everything else on the site is also working like it should.
I should also note that the file-uploading etc. within the window works - it's just the navigationi/pagination and "thumbnails" view that isn't.
