File permissions seems correct set to owner www-data and 777 on all installation / core files

seems to be frontend. I deleted the js folder in appdata_xxx folder and the js got recreated. The css is broken so i tried deleting that folder to, but the css does not get recreated.

the nextcloud app works fine and can access the installation but the webfronend still gives errors.

Ok so i finaly solved it, by deleting all entries in oc_filecache, now the site is responding again, still have a few erros, but i might be able to resolve thoose. i hope
