Switch from SQL lite to My SQL

Hi, I’m running Nextcloud on a webspace. I installed it with setup-nextcloud.php and had no chance to select mySQL as Database. At first I have been asked to create an AdminAccount - after that the screen changed. Is there a way to activate MySQL now instead of SQL lite?

Yes that is possible:
You can fin the explanation on this manual page:

Thank you Tom. I couldn’t do that in this way, because it’s not my server.
But I solved the problem: I created a new Nextcloud-folder and runned setup-nextcloud.php. I found out that I have to select the database before creating an account. Now it works.
