Survey doesn't stop loading after submission & results not saved (SQL-type question)
I have a single-question (SQL-type) survey. Link is here: https://www.spielatus.ch/joomla/index.php?option=com_communitysurveys&view=survey&id=4&catid=88&Itemid=464&skey=XDyMvr9nH6dkuz1K
When you enter some input and click the submit button, it keeps on loading (see printscreen below). It seems as if the result is stored, but no answers are included (empty result).
Question in Backend looks as follows (i tried with and without the custom answer textbox...both wasn't working):
Would appreciate any help.
