Login with the given administrator password and go to ""Posts"" -> ""Categories"". Enter a new category name, and category slug. Then click on ""Add"". Nothing happens. Because it's a webhost i don't have access to the PHP logs, and ini_set() doesn't do anything. Neither does an .htaccess with display_errors/display_startup_errors. I can reproduce this everytime with the above configuration with ff3.5.3 on Linux and Macintosh. It works fine with Safari. The javascript console error is: Warning: Unknown pseudo-class or pseudo-element 'input'.
