Hi, I installed 7.5.4 Plesk and did the hotfixes. Now and then I can not use the CP. Sometimes I can't login, sometimes only part don't function. At this moment I can't login. When I open the http://....:8443 for the CP I get this error: Fatal error: Unhandled exception in C:\Program Files\SWsoft\Plesk\admin\plib\common_func.php3 Is there another fix or something? Snef.
