I have several sites that I've refrained from upgrading to Joomla 3.8.10+, I have upgraded one site to J3.8.12 and disabled caching at the joomla global settings level. This appears to be working for me. But I'm also on Fabrik standard release 3.8.1 and wonder if I should consider a github update yet, or wait for the official release for J3.8.12? I currently have no functional issues with global caching turned off at the Joomla level.
