UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support Uncaught Error in class.phpmailer.php

The PHP Function "ctype_alnum" was NOT found on this system.

The "ctype_alnum" function should be installed by default on PHP 4.0.4+, PHP5, PHP7, PHP8. If this function has not been located on your machine please install it or choose a different available PHP version.

Thanks for the code. Any idea why it is not included on the system or somehow supressed by .ini setting? I searched the php.ini for ctype and/or alnum - I find nothing.

PHP Info page in my server control panel reports specifics 7.4.10 with Sep 9 2020 06:35:57 build date.
