CMS errors after upgrade

Hello,
I have just upgraded from 1.8.12 to 2.0.1. I followed this steps https://xibo.org.uk/docs/setup/upgrade-manual-custom-install
I had a problem, but I can solve it following this steps
Upgrading to xibo v2, unable to do database migrations

Now the CMS has some errors.
1. All values of location (in Display Setting Profiles) have been erased. I tried add new values, I clicked on save button without errors, but changes aren’t saved.
2. I can’t change setting values. When I click on save button an error message appears.

Error message after I change SERVER_MODE value in DB.

Does the url you use to access the CMS end in /web ?
Also do you see multiple SECRET_KEY in settings.php file?
