I have a rule that I have been using on one server for several months now. it is:
RewriteEngine on
RewriteRule ^/forums/f([0-9]+)/s([^/]+?)$ /forums/forumdisplay.php?forumid=$1&s=$2 [L]
I need to move the site to another server, but that server is not liking this rule. Specifically, it is failing on the regex with this error:
RewriteRule: cannot compile regular expression '^/forums/f([0-9]+)/s([^/]+?)$'
I am sure this works on another server. Any ideas?
