Greetings . . .
The last step in my upgrade plan was switch out the trailing PHP version we have been running for years.
I got word from one user of a strange error so I checked the server logs:
20220313T160723:
www.inliners.org/ubbthreads/ubbthreads.php PHP Fatal error: Uncaught Error: Call to undefined function ctype_alnum() in ./public_html/inliners/ubbthreads/libs/phpmailer/class.phpmailer.php:1461
Stack trace:
#0 ./public_html/inliners/ubbthreads/libs/phpmailer/class.phpmailer.php(1502): PHPMailer::isShellSafe('webmaster@inlin...')
#1 ./public_html/inliners/ubbthreads/libs/phpmailer/class.phpmailer.ph
I went to the control panel and tried to send an email from the Webmaster account. Fails every time.
Could the upgrade from PHP 5.5 to PHP 7.4 be the culprit?
Should I fall back to the old version? Or is there perhaps a control panel setting that needs to be tweaked?
regards,
Keith
