I installed the same versions of OST and OSTA in youor demo and my Tickets page is completely fried. Many of the pages are OK, but the menus and content on the tickets page are not working. Would it be possible to zip (after stripping out ost-config.php and other files) your demo for 1.12 and make it available?
I’m deploying a new ticket system and was hoping to use 1.12 since there are a number of improvements.
