Thanks a lot for your help.
I've read the link you gave and understand what's in it.
What I don't seem to get is that until about 3 days, all my listings, even the ones on the eBay PH site were seen the Showcase and the Store Window.
What I mean is, I have listed items on the PH site several times already and it was automatically loaded (after about 3 hours) to my Active Listings which in turn comes out in the Showcase and the Store Window.
About 72 hours ago and after listing an item on the US Site, everything I started to list on the PH site was never updated.
I was wondering if you guys could help me fix this problem so my listings in all sites would be updated. By the way, the language on the PH site is English so there shouldn't be a problem with that.
Thanks a lot.
