Code:
https://portal.lifepanel.eu/survey_completed/764735?token={TOKEN}&sid={SID}
So it cuts this long URL down to:
Code:
https://portal.lifepanel.eu/survey_complete
?
This is weird.
Also, your error description is not the best. Because from what I understand now, the END URL is actually loading, just not the correct one. So there is a redirect happening, but the whole URL is cut off in the middle of the word "completed", which is weird. So after 35 digits it gets "cut off".
Did anything else happen on the server between deactivating and reactivating? LS update, server update, database update, etc?
From what I understand, in Limesurvey there is still the full URL in the END URL field of the survey, correct?
What happens when you copy the survey and test the copy? Same issue?
Did you try to delete the URL from the end url field and insert it again?
