I can not log in to NC with PHP 7.2

[zoo3]

I currently run Nextcloud with PHP 7.1. I tried to run it on PHP 7.2 soon. However, when I made it to PHP 7.2, I could not log in to Nextcloud. I enter the user name and password and press the login button. Then the login screen is displayed again. “Password is wrong” is not displayed. At this time, nothing is recorded either in the server log or Nextcloud log.

I set the memory cache to APCu only as in the topic below, but it did not solve it. I am clearing the cache of APCu. I also restarted the server.

Internal server error going from PHP 7.0 to PHP 7.2

Dear all, that seems to be a common issue but I was not yet able to find a solution. Currently im on Nextcloud 13.0.5 with Ubuntu 16.04.5, Apache2 and PHP7.0 First I tried a Ubuntu upgrade to 18.04, workd fine but broke my nextcloud due to php so I fall back on my snapshot I did before and updated to PHP 7.2 using this manual: https://ayesh.me/Ubuntu-PHP-7.2 This is what im coming from root@nextcloud:/home/ncadmin# dpkg -l | grep php | tee packages.txt ii dh-php …

Do I have missing work to change from 7.1 to 7.2?
*I can use NC if I return to PHP 7.1.

The cause was a description mistake of “session.save_handler” in PHP.ini.

Could you by chance explain further what the solution was?
