I’m not able to reproduce this, currently, so until I do there’s nothing I can fix… however with two people reporting this it seems like less of a coincidence so maybe you can help me figure it out.
I’m looking at the comparison between 5.9.2 and 5.9.3 and I can’t see any code changes that’d affect this either….
What’s your specific setup? Do you have any non-default settings r.e. user registration? Do you force user registration before booking, or do you have no-user mode active?
@donchulio the screenshot doesn’t help me as I don’t speak German ?? so I’m not sure what the error is (Assuming there is one there). Looking at events on your site, it seems that there’s no booking form… is it still broken or is there another issue I’m not seeing? It seems like you use google docs to take bookings (I don’t have permission to see the doc).
@zininweb A URL might be helpful although I’m not sure it’d help me reproduce anything. Have you tried switching themes temporarily?
