I had that happen after I had somehow managed to actually make a duplicate page, then I deleted that duplicate page and redirected its URL to the first. But even if you have no actual duplicate, you can still do that with something like this in .htaccess:
RedirectMatch 301 ^/page/3/$ http://www.mysite.com/page/
RedirectMatch 301 ^/page/3$ http://www.mysite.com/page/
Ok, so I’m having a similar problem but with an extra wrinkle that I can’t seem to iron out.
My problem is I need http://www.themarketinggarage.ca/blog/2 redirected to http://www.themarketinggarage.ca/blog/.
I can’t just redirect everything after /blog/ because then I will lose my /blog/page2 (the proper pages)
Thanks.
@ Skylar_MG: It is seldom that two questions are identical, so you should start your own thread. However, this will explain about redirects not always having to redirect absolutely everything…
