Re this thread: http://www.litespeedtech.com/support/forum/showthread.php?t=6746 I could not update LiteSpeed which was giving me a license version error. So I opted to upgrade to a 2-CPU license to solve the license version error and check out caching. I requested and received a trial license. I changed my LiteSpeed license via the CPanel GUI and it would not accept it. The error message said to upgrade manually, which I did. The manual upgrade failed (I did not copy the error message) and LiteSpeed would not restart. At this point everything LiteSpeed is dead, including the LiteSpeed admin. Any ideas?
