I thought I had some other, weirder problem where items were simply not shown by Omeka or somehow not recognized but I think this is even stranger than I thought.
Our collection has 1858 items but clicking Items in the admin page you’re shown a single item. The public page shows all 15 as set in the appearance settings. Doing an advanced search for item IDs of 200-400 shows almost 200 items but still only shows the single item on each results page. The Next and Previous page arrows above show there were 124 pages, but only 1 item shown at a time. I checked the Thanks, Roy appearance settings to see what was set there and the max items per page was 15. I changed this to 10 and suddenly that page counter shows 186 pages but still only shows a single item. Has anyone encountered something like this? If I change max items per page to 1 it shows all 1858 pages, but of course that’s kind of useless.
I just finished properly upgrading from 2.7.1 to 2.8 following an upgrade that was probably not done properly (2.6 to 2.7 probably) but functioned. This upgrade didn’t ask for a database upgrade. This is self hosted on Ubuntu 20.04 LTS, I can fetch the LAMP etc. versions if that helps
