When  a visitor clicks the comlete button, the paga "hangs". It will not go to the redirect or thank you page.

I tried to export the survey, but then I get  a blank page.
Because of  the hanginh I wanted to export and import to another site, where the surveys do end correctly.
(on that one export survey also gives blank page).

Hope that someone has suggestions where to look.

Thanks in advance,

best regards
