Fluent SMTP Plugin breaks Gravity Forms

Hello,

When I submit my gravity forms registration, with a setting to send an e-mail notification after submission, it seems to break the form submission.

With Fluent SMTP off, submitting the Gravity Form goes through. When I turn on Fluent SMTP, I get a wordpress critical error.

I’ve added the e-mail used to send the registration e-mail in gravity forms, into Fluent SMTP and tested it. I do have a php log, but don’t feel comfortable posting it here.

I’m not sure what the best solution there is, other than hoping you guys can fix this or trying a different smtp plugin that doesn’t break gravity forms.

Any ideas or suggestions?
Thanks
Michael
