Hi! When I use the 3-Click ComfortUpdate to go from 1.91+ to 1.92+, it says everything is OK and executes the first two steps fine. On the third and final step, it displays some information on the page (see below) but then nothing else happens and the upgrade does not occur.
Just found out that this was a known bug in earlier versions of 1.91+. Getting one updated PHP file fixes the bug (details below). After updating that file, running the ComfortUpdate works.
