Hi,
1st possibility:
Your website is having a JAVA conflict problem which prevents our Zoom Effect works properly.
If you provide me a LIVE URL where i can see extension installed but not working, i can point out the problem.
2nd possibility,
Check your Virtuemart version. IF you are using Virtuemart2, then make sure its version is Virtuemart 2.0.6 (or above)
3rd possibility;
You are using a 3rd party template for your Virtuemart Section.
Please check your FTP server and look for this PHP file:
/templates/<yourjoomlatemplate>/html/com_virtuemart/productdetails/default.php
If this PHP file is exist, email me this PHP file, i will make a little edits to this file and our zoom effect will start working.
