Hi Everyone,
For the past two weeks, I’ve been encountering an HTTP 500 error when trying to access my Nextcloud web interface (although the mobile and desktop apps are working fine).
Unfortunately, I don’t have many logs to share, but the only relevant error I could find is:
2025/05/20 16:16:39 [error] 908794#908794: *138 FastCGI sent in stderr: "PHP message: PHP Fatal error: Array and string offset access syntax with curly braces is no longer supported in /data/www/nextcloud/index.php on line 2" while reading response header from upstream, client: *.*.*.*, server: cloud.*.fr, request: "GET / HTTP/2.0", upstream: "fastcgi://unix:/var/run/php/php-fpm.sock:", host: "cloud.*.fr"
I honestly have no idea how to fix this — any help would be much appreciated!
Happy to provide more information if needed to help resolve this issue.
Thanks
