Hello

After updating from 2.4.6 to 2.4.13 users get a blank page and "No authorisation" after clicking the "Preview" or "OK - Submit" buttons. What can be the cause of this?

Update: It's obviously theme-related …

Yes, it is.

… because everything works fine after I changed from my custom theme to the default theme.

Please pay attention to the log for theme related changes that tracks the changes since version 2.4.6 in headwords.

Tschö, Auge
