I am experiencing the very same problem after updating WP Mail SMTP from the previous version to 2.0.1. I’ve followed your advice, cleared the caches, disabled/enabled the plugin, re-enterered the settings for my ‘other SMTP’ server.
Please advise.
“Fatal error: Uncaught Error: Call to undefined function eregi() in /home/company/public_html/wp-content/themes/district/template-contact.php:41 Stack trace: #0 /home/company/public_html/wp-includes/template-loader.php(106): include() #1 /home/company/public_html/wp-blog-header.php(19): require_once(‘/home/company/…’) #2 /home/company/public_html/index.php(17): require(‘/home/company/…’) #3 {main} thrown in /home/company/public_html/wp-content/themes/district/template-contact.php on line 41”
