Template works fine with OpenCart 22.214.171.124. We’ve checked the link you have provided, but see you have switched to Pavilion default and everything works just fine. Generally all theme versions use the same codebase and only theme settings differ, so installed there shouldn’t make any difference.
We’ve worked really hard to build the BurnEngine product with all these features. This comes on a hard price though – OpenCart is not the type of software that behaves well when you need backwards compatibility, all different versions have their own quirks and there are always problems that we might have missed.
