Hey guys ,
one of my sites were having a very high mysql load and was slowing the site big time so did a fresh vbulletin install + db restore
However now the urls are like this : http://www.siteurl/showthread.php.....
When it should have been like this : http://www.siteurl/326842-title.html
* i had vbseo installed before , i installed it again and enabled but the urls haven't changed , any idea how to do it ?
