It's mostly some type of browser issue. Adblock is not friendly with WC, and again, I remind people that ads are one of the main ways WC supports itself.
Blocking them only takes away income from the site.
My point: I paid to have the ads removed.
I don't use ad block on the WC site since I use IE to access it. The adds are still there even though I paid to have them removed.
Can you be more specific about the type of "browser issue" it may be?
