Login Module

Hi, I'm trying to set up my store but I have problem with the login module. It is not working correct with virtuemart pages. When pops up the window is very small but if you choose the second choise "ΕΠΙΚΟΙΝΩΝΙΑ" the pop up window is ok.

Hi

Looks like even product page is not showing properly. Please send me an access to joomla panel and ftp I'll see what can be wrong.

Hi

Please replace file: gk_bikestore/js/gk.scripts.js with the one attached

I've replaced the file but it's still not working correctly.

Hi

Thank You for access. Problem was with an extra CSS file being loaded by Virtueamart. I disabled it and now everything works great.
