You already got offered what you like to get, but if you don't know basics like URLs or directories that may not be cached in phpbb you are overwhelmed with a plugin. A plugin also need such information! Why complain about Litespeed and a not existing cache plugin for phpbb if the problem is sitting in front of the monitor?
How am i supposed to know the name of phpbb cookies and urls that should be excluded. The whole point of me paying you is for you to figure this stuff out because i can't.
What you're asking me is to do the work for you and then pay you for just few seconds edit. Seriously! This is xenforo, if i know the cookies name, don't you think i can edit this text myself?
# LiteSpeed XenForo cache
<IfModule litespeed>
CacheLookup public on
RewriteEngine On
# cache
RewriteCond %{HTTP_COOKIE} !(xf_lscxf_logged_in|xf_user|xf_session_admin) [NC]
RewriteCond %{REQUEST_URI} !/install/ [NC]
RewriteRule .* - [E=Cache-Control:max-age=360,E="cache-vary:xf_style_id,xf_language_id"]
# no cache
RewriteCond %{HTTP_COOKIE} (xf_lscxf_logged_in|xf_user|xf_session_admin) [NC]
RewriteRule .* - [E=Cache-Control:vary=loggedin,E=Cache-Control:no-cache]
</IfModule>
And that's beside the extension that you wouldn't make which xenforo has that sets up cookies for places xenforo doesn't produce. So chances are even with the htaccess rules that you might have provided, i was still going to have issues because like Xenforo, phpbb must have places where no cookie is set but that should be excluded from lscache.
The whole thing sounded weird and i lost interest. I actually know stuff, i can't imagine what your attitude will be with people who don't even know what htaccess is. With all due respect, you clearly don't understand how to even offer your services and think the client has to do the work and also pay you lol
