Hi Josef,
Do you have this error message ?
Attempt to assign property "cssClassName" on array
And what you did, reinstalled SPPB 4.0 with SPPB 3.8 instead of as I told you to recover full website from backup??
We are trying to fix it, but BACKUP is quicker method.

If you will install SPPB 4.0.x ones and edit page, article, sppb module ... then it may be too late to reinstall with SPPB 3.8. that's why ... recovering from backup is 100% safe method.
SPPB 3.x code will updated and supported till Aug 2023, so you have a lots of time to upgrade in next months.
