Our client received an email from Foxy:
Subject: Transaction 41514125 for [store] had a template parsing issue.
The transaction went through, but your store's twig templates may have a fatal error which must be corrected. Please go to your FoxyCart admin and attempt to save all templates including category admin and customer email templates.
We re-cached the pages, but can't think of anything else. We are using 0.7.2 for this store, so Twig should not be a factor. Any suggestions? Should we upgrade to 1.0?
