Ok here is the think

suppose you want to submit a link to your mates wall,

You copy/paste a link and facebook generates title, image and description.

Curently i am working on http://www.compra.gr

When you want to submit this link (http://www.compra.gr) facebook generates characters that are not recognised.

When you want to submit http://compra.gr/index.php?option=co...d=35&Itemid=54

Facebook generates title,image and description normally.

I know that facebook takes the information from metadata. I corrected the metadata, however nothing happened.

Please help me if someone has a a clue what is going on.

Thank you in advance.
