First, a big compliment to the development team – this form builder plugin makes me happy! 😉
My issue: If I press the submit button on any form, the confirmation message will not be displayed and the form is still containing data (not reseting). But the e-mails are sent and the entries are present in the backend.
I have now done various tests (exclusion method) – now I know: There are probably conflicts with my theme. If I use the Twenty Fifteen Theme it works perfectly.
