Hi,

Are you using the latest version of plugin (1.11.05)? Issue was reported earlier and must be fixed in latest version.

We remain at your service.

We would really appreciate your feedback at WordPress.org!

Yes, we are using Version: 1.11.05.

On Genesis.

Do you get PHP Warning or Fatal error at this moment?

We just noticed that error from your log appeared on 25 July 2020, but it was fixed on 27 July 2020 in 1.11.05, it's about PHP Warning.

If you are getting Fatal Error upon form submission now, can you try to remove "e2pdf" shortcodes from success message/mail notification and test form submission without?

We remain at your service.

Thank you..

Yes, we are still receiving the following error:

I went to my host, Siteground... we thought perhaps WP Memory Limit was the issue and he raised it to: 768MB. I received the the message above.

I turned off 'notifications' in the gravity form, re-submitted and did not receive the error.
I turned on 'notifications' in the gravity form, re-submitted and DID receive the error.

The email notification is:

Thank you for entrusting your property with Paradise Palms Property Management.

thank you

I just checked another form, it's happening on that one too..

Did you try to remove [e2pdf-attachment id="11"] from notification and submit form?

In any case, submit please support ticket here: https://e2pdf.com/support/request

If possible, include also please FTP details.

By some reason wp-db.php on mysql request taking all memory and it can be caused as due E2Pdf as due other plugins, so we need to make some tests and find out on which request it's failing...

We remain at your service.
