hi,
this last week I’ve been receiving error emails whenever the WPForms is submitted. The subject of the email is “Post SMTP email error” and the content
“You getting this message because an error detected while delivered your email. For the domain: https://fantasticphotosprague.com The log to paste when you open a support issue: Bad Request(invalid_grant) ”
I don’t receive the content of the submitted message.
I also have WP Mail SMTP installed. When clicking on the Test Email button it gives the error “There was a problem while sending the test email.”
The tech support of hosting provider Bluehost checked the email routing and suggested I contact WPForms as they believe the issue is with the plugin.
Can you help?
Thanks!
Kind regards
Doug
