Thomas, did you upgrade and restore? If so, try just doing one at a time, starting with restoring to the exact same code base before initiating an upgrade process to minimize complications.
If/when upgrading, check to see if all the upgrade scripts ran successfully, or if any were not executed. iirc, there's some discrepency betwen the naming of one of the core upgrade filenames and the upgrade-script file names that the system searches for on startup. maybe zzz-postload.tcl
The error.log file indicates when an upgrade script is loaded/executed, so you can grep for the filename.
See also this thread: https://openacs.org/forums/message-view?message%5fid=182098#182098
and the part of https://openacs.org/doc/openacs-5-1/upgrade-4.6.3-to-5.html that deals with zzz-postload.tcl
Maybe there is something there for you to work with.
Good luck.
Torben
