Ha, got it! It’s the act of selecting ”Admin” from the ”admin” dropdown menu (top right) that triggers it. Nothing else seems to do it (”Users” from the same menu for example doesn’t trigger it).

There’s now also this in the log:

File does not exist: /var/www/userhome/mummila/sites/mummila.kapsi.fi/secure-www/oc/assets/dist, referer: https://mummila.kapsi.fi/oc/index.php/apps/gallery/

But I’d wager it’s completely unrelated to the other ”not exist”, as I only activated asset-pipeline yesterday. Browser’s JS log says it’s missing assets/dist/jquery-migrate.min.map; it doesn’t say anything about the data directory that the server log complains about.

While poking around, I also noticed that for my non-admin OC user, selecting Pictures from the Apps menu brings up the Pictures view, but it fails to load any pictures. The loading spinner just keeps spinning forever. The admin user’s Pictures view does work, i.e. it actually loads the pictures too. I’m not sure if this is related to the log issue either, but thought I’d mention it anyway.

Any ideas on how I can narrow this down further?
