I'm sorry and I've posted that I could not find where to get PHP to
actually log errors...until now. I set it in /etc/php.ini, no difference,
Then I found /etc/php-fpm.d/www.conf, no difference. And yes I restarted
httpd each time. Then I found your debugging plugin
<https://squirrelmail.org/plugin_view.php?id=228>. And it wasn't until I
saw "11. Tweaks" option and then:
Configuration tweaks
7.  Allow remote configtest     : false
8.  Debug mode                  : SM_DEBUG_MODE_OFF

Once I enabled those, the first warning I got was this:
    WARNING: undelete is NOT COMPATIBLE with this version of SquirrelMail

And then I saw these errors:
[31-Jan-2022 02:34:22 UTC] PHP Notice:  session_start() [<a href='
http://www.php.net/function.session-start'>function.session-start</a>]:
Ignoring session_start() because a session is already active in
/usr/share/squirrelmail/functions/global.php on line 129

[30-Jan-2022 21:34:52 America/New_York] PHP Fatal error:  Maximum execution
time of 30 seconds exceeded in
/usr/share/squirrelmail/functions/url_parser.php on line 60

So I suppose I can extend the time out? Or is there a better option?

FWIW line 60 has this:
    while (preg_match('/' . $Email_RegExp_Match . '/i', $sbody, $regs)) {
