this is a really strange one.
I've set up a bunch of pins on Pinterest linking through to our services which all work fine. Then I decided to do the same on our blog articles (we use Wordpress), yet everytime I click the link (and I've done this on different computers) the link goes to a 404 page on our site. However the link is valid and if you right click the pin and open in new window it opens fine.
I have contacted Pinterest who are next to useless. I have also tried different browsers, different computers and different Pinterest accounts.
I can't see any weirdness in my htaccess files causing this so I'm a little stumped. Any suggestions?
