I've vBulletin forum installed in /forum directory on a website.
I'm trying to redirect /forum/xyz/ to /forum/abc-xyz-def/
I tried this rules but none worked
In the .htaccess file of root
RewriteRule ^forum/xyz/ /forum/abc-xyz-def/ [L,R=301]
I also tried above in the /forum/.htaccess but still didn't work.
