Hey there,
I have different multi-page forms.
From time to time when going from first to second page the following errors appear:
Warning: Invalid argument supplied for foreach() in /machform/includes/entry-functions.php on line 355
Warning: Cannot modify header information - headers already sent by (output started at /machform/includes/entry-functions.php:355) in /machform/view.php on line 99
This happens
1) Randomly on existing forms
2) On every duplicated form
If I open the form in the form editor and just save it, the problem is usually solved. But every Adwords-Click costs money. Do you have any ideas what I could try?
Kind regards
Tobias
