I have put together a package that fixes the BTS problems with several mods.

The following mods are now fully incorporated into the BTS system, and will no longer break your template:

All Products
Gift Voucher System
Printable Catalog
Down For Maintenance
Affiliate InfoBox

You can download the upgrade package from

Here

Be sure to read the readme file included in the package. Updating is easy, but read the instructions first. And remember, ALWAYS BACKUP YOUR SITE BEFORE INSTALLING UPDATES!
