So i have upgraded to the last version, updated all of my plugins and everything went fine except the Ajax chat, it is causing problems.. i deleted the ajax plugin via FTP access and uploaded new update again, also updated it from the admin panel as well, but every time i activate the ajax plugin it is laggin my site and it wont let me click on any single button or anything.. i cant even click on the Mailbox, Notifications, also cant see anything when i scroll my mouse eon my name..
