Hello, following the update from Nextcloud 31 to 32, I can no longer access my server’s web page. After doing some research, I realised that this is potentially a PHP issue; here are the logs: Is it possible to roll back using a backup, to restore a working server, whilst I set up a second machine with the current requirements? - Nextcloud Server version _(e.g., 29.x.x)_: - `31.0.14` - Operating system and version _(e.g., Ubuntu 24.04)_: - `Ubuntu 22.04` - Web server and version _(e.g, Apache 2.4.25)_: - `2.4.52` - PHP version _(e.g, 8.3)_: - `8.2.28` - Is this the first time you’ve seen this error? (Yes / No): - `yes` - When did this problem seem to first start? - `after update 32.0.15` ### Log entries #### apache.log ```auto [Fri Sep 11 22:02:53.873147 2026] [php:error] [pid 439702] [client 66.132.195.111:21610] PHP Fatal error: Class OCA\\GroupFolders\\Versions\\VersionsBackend contains 1 abstrac> [Fri Sep 11 22:05:41.755309 2026] [php:error] [pid 440946] [client 192.168.1.254:36712] PHP Fatal error: Class OCA\\GroupFolders\\Versions\\VersionsBackend contains 1 abstract> [Fri Sep 11 22:05:42.025789 2026] [php:error] [pid 440947] [client 192.168.1.254:36728] PHP Fatal error: Class OCA\\GroupFolders\\Versions\\VersionsBackend contains 1 abstract> [Fri Sep 11 22:08:01.634910 2026] [php:error] [pid 440953] [client 192.168.1.254:64520] PHP Fatal error: Class OCA\\GroupFolders\\Versions\\VersionsBackend contains 1 abstract> [Fri Sep 11 22:08:04.915950 2026] [php:error] [pid 439702] [client 192.168.1.254:64521] PHP Fatal error: Class OCA\\GroupFolders\\Versions\\VersionsBackend contains 1 abstract> [Fri Sep 11 22:10:42.043050 2026] [php:error] [pid 439691] [client 192.168.1.254:41454] PHP Fatal error: Class OCA\\GroupFolders\\Versions\\VersionsBackend contains 1 abstract> [Fri Sep 11 22:10:42.045671 2026] [php:error] [pid 440947] [client 192.168.1.254:41440] PHP Fatal error: Class OCA\\GroupFolders\\Versions\\VersionsBackend contains 1 abstract> ``` Thank you for your feedback ---

Hello, I tried to restore from a backup located at /data/updater-xxxx/backup using the rsync command. I no longer get the 500 error, but I’m now getting a new server error: ```auto ‘scriptName’:‘/index.php’,“message”:‘Class \\’OCA\\\\Files\\\\Controller\\\\FilenamesController\\‘ does not exist’ ``` I have carried out a ```auto root@nextcloud:/var/www/html/nextcloud# sudo -u www-data php occ integrity:check-core - EXTRA_FILE: - LICENSES/GPL-2.0-only.txt: - expected: - current: fb956f64a9d0647514d7bd868747c46842e9e3b10ad1b3ff8f18908b9986fded8928e55d3d23b43676c918e971f0d9b7f60f2fef8941fb867a43422c31bc4655 - 3rdparty/guzzlehttp/psr7/src/Rfc3986.php: - expected: - current: 8444a5252a91f6bebf1aef4fe876acb4504c5dbd44e24ce165e9c8873979bfe398ab0bc1af8b9914b297c59eb7edb619f2c2aed0ae09897e6768f08371a227a6 - 3rdparty/guzzlehttp/guzzle/src/Multiplexing.php: - expected: - current: e59e30dd9851f0192afe422b5755d8fd4abb7060c2b33ee75bf20ddc60302c9dcae3f97e02f8eed7cef3376f1f04844744182ed09e42cbc50272587f78c9b415 - 3rdparty/guzzlehttp/guzzle/src/TransportSharing.php: - expected: - current: 2871ada6cc3b61310690fac52973c9aaeeb93640c67cbb6442ea8e33400fa0f381ca9e454c40abd0e26ae4a647688e21f419abe9c70d252dc4abffacb0646678 ``` I’m stuck and I can’t find any information about this online. Can you help me? ---

I tried the command: ```auto sudo -E -u www-data php occ upgrade ``` but this is the message I got: > No upgrade required. > Note: This command triggers the upgrade actions associated with a new version.

Have you upgraded back to v32 first? ---

Yes, I’d updated from 31 to 32, but I got a 500 error. I tried restoring a backup, but that wasn’t the best idea I’ve ever had… ---

I ran the update again via the SSH command line; the update went through successfully and I was able to access my Nextcloud server again. Thank you. ---

Hi, i experienced a similar problem after updating via ncp-dist-upgrade. I experienced Mal-function as well (e.g. error 500 on Web browser, not working clients). Solution for me was updating php-oc-cache via ncp-config. ---
