We migrated to a new site. But I just checked this thread on the old site, and nothing is missing.
As per my response on another thread, I think the only way I can move forward with this and the other remaining stubborn issues is to install an Akeeba clone of your site here, so I can create a PHP Storm project on it and do line level debugging. I did try to replicate what you are seeing, but can't. Which is not wildly unusual, as issues sometimes only arise with specific combinations of settings, some of which may not seem relevant. And obviously if I can't replicate it, I can't fix it.
We're basically moving away from "all you can eat" subscription support, and to a "pay as you go" system. Sub support kinda worked in the early days, but as J! itself has lost market share, and Fabrik has become more complex, and the apps people create and the issues they come up with become more complex and corner case, we just can't do the "all you can eat" thing any more.
I'm working on a way for people to buy support hours, and a ticketing / time management system, but that won't be ready for at least a week or so.
Meanwhile, I'm happy to install your site here and fix this stuff, as long as you'll do a Cub Scout's Honor thing to buy an hour of support, once that's up. I don't have exact pricing, but an hour will be in the same ballpark as a Pro sub.
