I have a serious problem in that users cannot access my website after completing or canceling an order unless they delete their cookies! As soon as the user hits the PayPal page, they will not be able to return to my site, instead seeing a page under my domain saying, "No Results Found."
I already tried changing my theme to Twenty Ten and the same thing happens, so it isn't a theme issue. I also contacted PayPal's support team and they told me it wasn't their problem. The only other plugins I have installed aside from eShop are eShop Text Mangle and Jetpack.
Help is desperately needed-- My customers are trying to come back for more, but they are unable to!
