Hi,
I just re-sent the download link to your email address to let you download the latest version of VM2 Template - FlexibleMart (it is now v2.1), please apply this instead. It is fully compatible with VM2.0.12. Please apply this new version, then if the problem persists, please let me know.
By the way, from now on, you can click the same link to download the latest version whenever you want.
Cheers.
