I’m adding this as a new post, because it doesn’t seem to be getting any attention under its old heading of 7.4 favorites, and I’m worried that is because everyone just thinks people should upgrade. Something is wrong about the way that the upgrade path works (at least with certain versions along the way of the upgrade). If you do a fresh install of 7.7.2 it works fine, but if you upgrade from 7.3.x to 7.4.x to 7.6.x to 7.7.2, they don’t work.
Please review my troubleshooting so far, and make some suggestions…
Any help is appreciated,
