Error upgrading to php 8

Good afternoon,
a few weeks ago I upgraded my escriptcase version to php 8. Since that change my login screen in development shows me this message.
Can anyone help me?
Has it happened to anyone else?

Can it be that you upgraded your SC instance and not install fresh? If not, then something must have been wrong with the install. I would do a fresh install on a separate folder anyways.


Hello, the installation is new, on a new server as well. But the project was initially developed on a server with php 7 and was restored from a backup on this new server with version 8.

Could the error be about (parts of) your event code? There are compatibility issues between PHP 7 and 8. Verify the character encoding of your application, database and if necessary set it in the application section of your program.
