I just saw one of the comments on this support forum and the 'is it broken' votes is 0 to 1.
Sounds like you haven't heard of this being a widespread problem, though. So you don't think there is a problem with updating WP?
As far as migrating, I guess I'll have to think through that more. I guess post types and templates are not one and the same.
Part of it is risk management. This plugin is the backbone of my site, and I try not to rely that heavily on plugins if I can help it. Are you planning on continuing to support this plugin?
Thanks for responding.
