Title: Error on Submit Last modified: January 28, 2017 --- # Error on Submit * Resolved [bmbingham](https://wordpress.org/support/users/bmbingham/) * (@bmbingham) * [9 years, 4 months ago](https://wordpress.org/support/topic/error-on-submit-6/) * So if I fill out my entire contact form and hit submit I get a 404 error. If I don’t fill out the whole contact form and hit submit I get this error: * “Fatal error: Uncaught exception ‘phpmailerException’ with message ‘Invalid address:( setFrom) ‘ in /home/bmbingham/pirateradio.productions/wp-includes/class-phpmailer. php:1023 Stack trace: #0 /home/bmbingham/pirateradio.productions/wp-includes/ pluggable.php(352): PHPMailer->setFrom(”, ‘Brian Bingham’, false) #1 /home/bmbingham/ pirateradio.productions/wp-content/plugins/contact-form-7/includes/mail.php(111): wp_mail(‘info@pirateradi…’, ‘”” Inquiry’, ‘Name: Brian Bin…’, ‘From: Brian Bin…’, Array) #2 /home/bmbingham/pirateradio.productions/wp-content/plugins/contact- form-7/includes/mail.php(18): WPCF7_Mail->compose() #3 /home/bmbingham/pirateradio. productions/wp-content/plugins/contact-form-7/includes/submission.php(258): WPCF7_Mail:: send(Array, ‘mail’) #4 /home/bmbingham/pirateradio.productions/wp-content/plugins/ contact-form-7/includes/submission.php(157): WPCF7_Submission->mail() #5 /home/ bmbingham/pirateradio.productions/wp-content/plugins/contact-form-7/includes/ submission.php(28): WPCF7_Submission->submit() #6 in /home/bmbingham/pirateradio. productions/wp-includes/class-phpmailer.php on line 1023″ * I’ve tried the default theme and I get the same errors.

If they do put an email address in I get a 404 error.

I guess the same problem probably happens even without Autoptimize. * Anyway, ignoring config validation alerts is not a smart idea.
