This really isn't a datafeedr error more of a theme problem. My title tags work great with the default wordpress theme. I brought the pagelines pro theme and now they won't work on the store pages. If you have a moment could you see if its a simple change I need to make? Or if I need to try to contact them about it. It doesn't seem to make a difference if I use the All in one seo or not. I tried reading there message boards and their answer 99% of the time is use AIOSEO.
