Hi, I just searched on Github and this issue has indeed be reported and was fixed for NC17. User report: > > > Steps to reproduce > Run Nextcloud on a server with PHP 7.4 beta version > Lookup warnings in PHP error logs. > Expected behaviour > No warnings. > Actual behaviour > Warnings about... Fix for NC17: > _Edit: Just updated the issue and asked for a backport 🙂_ A fix would come in the next release first. If you don’t want to update to NC17 yet, you could change the files manually. However this has the drawback of integrity check warnings in the admin overview. ---

Sure 🙂 If you need help with manually fixing the errors, feel free to post the mentioned lines (in the error messages) of each file and I can show you the necessary changes to these files, if you need assistance. ---

Nextcloud is working fine so long 🙂 I’ll just wait since Nextcloud 17 released on stable channel. ---

Seems that they added a block on PHP 7.4. When I enable 7.4 and run occ I get a warning that Nextcloud won’t run with 7.4. I am using NC 17.0.1 ---

Since the last upgrade of 7.4 nextcloud doesn’t work. Just the message “this Version…”. Roll Back to 7.2 solved the problem ---
