Form works - then once I add more fields, save and re-upload - it no longer sends mail
I'm using the current Form Builder as of today in DW CC. I've started with a basic Contact/Simple Contact form - made minor edits and uploaded all files to server. It works and sends email as it should. I add a few more fields and just hit 'save' to group message and content message. (I had tried always saving and resaving presets but thought that might have been my problem so this time I did not). I went to form function tab and noticed 'send email' was unchecked for some reason. I checked it - uploaded new files and form sent like it should. I did more fields, hit save twice without renaming or saving presets - rechecked the email box uploaded files - but this time the form no longer sends email. The URL is now appended with ?invalid=true.
Why - I've restarted this form 3 times now with same result.
