We managed to get size problems fixed. It was just a simple enabling product id in url.
The problem that remains is that add to cart stops responding. It does nothing at all. no matter how many times you click it. It does not add products to cart.
On the picture you can see problem number 2:
[attachment:1]joomsef problem.jpg[/attachment]
When cache is open and joomsef too we get this on "ask a question" iframe. It's the product page reloaded inside the iframe. If we close cache everything works fine. Same thing happens with mail to a friend.
We can't seem to get the why!
Example url with the problem is the following:
www.maxsports.gr/antrika-modas/modas-3/a...int&limitstart=0
P.S. Ρωτήστε για το προϊόν = Ask a question (greek only site)
