mybb Rewrite Rules

Hello i was working with mybb and renamed htaccess.txt to .htaccess

but it still looks like its not working so anyone knows how i can fir it ?
(i got lots of 404 errs and in mybb froums it said you need to rename htaccess.txt to .htaccess witch i’ve done later but its not working) is the url

all rewrite rules may not work under litespeed , anyway you need to restart openlitespeed to read the htaccess, it will not work like apache as apache will take htaccess rules dynamically openlitespeed dosen’t .
