My Nextcloud is on a webspace @ IONOS
Updated from 23 to 24 several times, corrected the errors so
24.0.8 was OK and running with no problems
Then I stated web updater again when I click finish maintenance mod and go on with update only a white screen is shown now!
When I call the cloud from another PC, same white screen
Pls help to solve this.
Many THX
PS: If you need more info, Pls. Let me know
THX
Just like me.
I don’t know what to do ?
Ok Let’s hope for experts to help 
I will not touch anything not to ruin more
BTW is your cloud also on IONOS webspace?
Yesterday i had the same problem on a SLES Linux Instanz.
Solution was to perform the update again using the OCC command commands.
After that, however, it shot up the graphics, which must be restored via design.
Many THX
Works also on IONOS webspace
Logos Background, Favicon, were gone at first look
BUT - working again
Many thanks also from my side.
@Paul1:
you have to execute the command occ upgrade in your nextcloud folder on the server.
I also using a IONOS webspace and I had to execute the needed command as follow:
php8.0-cli occ upgrade
depending on your php version you have to adapt your version.
Hope it will help you.
