Hi i have recently moved my forum from Mybb to Vanilla, so the index pages such as showthread.php now do not exist. This is a big problem for SEO, what do I do to redirect this to the home page?
In your .htaccess file:-
redirect 301 /path/to/url http://www.domain.com/path/to/new/url
Note the first url has no domain name, but the second one does.
