Hey Everyone, Thank you Alvaro and Jonathan for your help, I wanted to report back that I got this fixed and what the problem was in case someone else runs into this. An error in the plack-opac-error.log appears, and the same warning appears when I did koha-rebuild-zebra with the –v option: DBD::mysql::st execute failed: Unknown column 'me.exclude_from_local_holds_priority' I created a new instance, and found that column in the items table on the new instance but not on the old instance. I added the column with the SQL command: ALTER TABLE items ADD exclude_from_local_holds_priority tinyint(1) and that fixed it. I’m not sure why koha-upgrade-schema didn’t fix this. I have another instance that we stopped using and combined with an existing one. I tried doing koha-remove, then koha-restore, the koha-upgrade-schema on that instance and it didn’t work. I am concerned that there may be other database alterations between version 19.05 and 20.11.02.000 that also didn’t make it into the database. I found a reference to database changes on the wiki but it ends in the 3.x series. How do I find out what other database schema changes have been implemented between 19.05 and 20.11.02.000?
