I think I have a canonical issue going on on my site, and I want to try and fix it. But I'm a bit confused... I've been doing a bit of research on it, and I think I need to install a .htaccess file. I have no idea how to do this... Though, perhaps I can just use 301 redirect? I don't know how to do this either though... So I was wondering if anyone can advise which is easier, or better to do... and how I do it... Or, is there a wordpress plugin that can do it for me? Any info is appreciated, thanks.
