all of our forms stopped sending e-mails recently on our site. This has been an issue in the past on a different site, and was able to fix the issue with SMTP. We have done this and all of our forms are working except for two for some reason. Do you have any ideas on why that may be? I've also checked to see if there was a plugin conflict but it would still not send it after disabling all plugins unrelated to GF.
Note: These two forms are using the PayPal add-on, the rest are not.
