I recently did a restore of my nextcloud instance because a nextcloud update crashed the whole instance. I Instaled a new Image on my SD Card and then did the Restore. The Restore worked fine but now when i go to Nextcloud i get this Error:
This version of Nextcloud is not compatible with > PHP 8.0.
You are currently running 8.1.21.
I deleted the instaled php Version and installed PHP 7.4.33 but it still doesnt work.
Can someone Help me because i cant fix it on my own because im a Noob in Linux
