I am hosting my NC on a regular webspace at an ISP and did an Update from NC 271.5.1 to 28.0 via webupdater. The checks were all OK. After confirming to do the update, the NC website became empty / white and even after long time waiting, NC didn’t come back. It is dead.
In the config.php the maintenance is set “false”. No errors in the updater.log
Then I have checked nextcloud.log. All requests of the clients were answered without error until the time of the update. Immediately after the update each request of the clients is answered by an error message like this:
{“reqId”:“…”,“level”:3,“time”:“2024-01-18T15:22:25+00:00”,“remoteAddr”:“222.435.62.789”,“user”:“–”,“app”:“PHP”,“method”:“GET”,“url”:“/index.php/204”,“message”:“Class OCA\GroupFolders\Helper\LazyFolder contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (OCP\Files\Folder::searchBySystemTag, OCP\Files\FileInfo::getMetadata) at /home/www/nextcloud/apps/groupfolders/lib/Helper/LazyFolder.php#32”,“userAgent”:“Mozilla/5.0 (Linux) mirall/3.11.0git (Nextcloud, manjaro-6.6.8-1-MANJARO ClientArchitecture: x86_64 OsArchitecture: x86_64)”,“version”:“27.1.5.0”,“data”:{“app”:“PHP”}}
How can I get rid of this error?
