The forms are working correctly on the back end with notifications and see if the entries went in when logged in to machform.
However, for those filling out the form get a blank screen after they press submit. So it seems to them that it did not go through, although it did. It seems like most of our forms are doing this.
Form is on this page: http://www.worldharvestchurch.org/admin-links/requests-proposals-reports/prisonyouth-detention-outreach-report/
I have ran into this issue. It turned out for me that the notifications were not done correctly. Someone added two email addresses and used the wrong character to separate email addresses.
