Some modules cannot be installed on FreePBX 16

[AndrewZ]

I had to upgrade to FreePBX 16 earlier than planned, almost everything works well, with a few exceptions: two modules - cdr and cel - cannot be installed/upgraded due to php errors.
Is there any fix for that?

Fixed by this change in /var/www/html/admin/libraries/DB.class.php line 153:

if (!count((array)$dsn)) {

Is this a Distro install with PHP 7.4? I’m not able to reproduce this.

Non-distro, but with PHP-7.4, see prehistory.
