Hello,
Litespeed is a good apache/nginx replacement but it’s a pain to compile LSPHP to match PHP to ensure everything works and to resolve that, a plugin is needed, reason why i posted into Litespeed forum, they agree if enough people.
That’s also the reason why i invite you to vote for an Interworx plugin to be made by Litepeed here http://www.litespeedtech.com/support/forum/threads/interworx-plugin.9928/#post-82414.
Regards
