I am not sure every time I rename a board or a thread the redirect is not working! Old and new URLs show 404.

I started getting this issue after I enabled gzip compression here is my .htaccess code.

 # compress the files

AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/x-javascript

# removes some bugs

BrowserMatch ^Mozilla/4 gzip-only-text/html

BrowserMatch ^Mozilla/4\.0[678] no-gzip

BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

Header append Vary User-Agent

An example:
http://letsforum.com/Thread-SEO-signnals - can't access

Renamed it to:
http://letsforum.com/Thread-SEO-signals - can't access

http://letsforum.com/Thread-SEO-signnals...EO+Signals - can access
http://letsforum.com/Thread-SEO-signals?...EO+Signals - can access


Update!!!!!!!!

Used Firefox to change thread title!!!!!!!!

The thing is IE and Chrome show the thread but not Firefox?
