OK, I've confirmed that provider now says php is now at 5.3.24. I did a test and no notification was sent. Is it recommended to re-save the form and post again? Is there a format to use if multiple recipients are going to receive the form? E.g. firstname.lastname@example.org, email@example.com or firstname.lastname@example.org; email@example.com. Comma v. Semicolon.
And what if I have the option to go to php 5.4? Recommended?
Email addresses should be separated by a comma. If the email is still not arriving, you should also experiment with using different email address under the Settings > Notification tab. Use Gmail, Yahoo, MSN, etc. Doing this will help you rule out if there are email issues with a particular domain.
I would also recommend you publish that same form to S-Drive and run a test there. This way we know that if the email arrives when hosted on our servers, that points to your server still having some issues.
If you do not have an S-Drive account already, you can signup for free here at www.coffeecup.com/sdrive
