PHP Fatal error: Uncaught TypeError: array_key_exists()

I experienced this error twice on the 12/19.

PHP Fatal error: Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array, null given in /usr/local/www/pfblockerng/pfblockerng_category_edit.php:447
Stack trace:
#0 {main}
thrown in /usr/local/www/pfblockerng/pfblockerng_category_edit.php on line 447

Running on Netgate 5100
Running pfBlockerNG 3.2.0_8
Running: pfsense 23.09.1-RELEASE (amd64) built on Mon Dec 11 13:24:00 EST 2023 FreeBSD 14.0-CURRENT
Please advise and thank you in advance

Easy path :
In this order :
Start by upgrading pfSense. You've missed the fact that pfSense 24.11 is out.
This will, as a side effect, upgrade your pfBlockerng to _16.
Which will, as it is a new version, also make the issue go away.

I wasn't sure if I could upgrade pfsense to 24 on my Netgate 5100. Has anyone else done this upgrade on Netgate's 5100 appliance? Would appreciate if I knew that someone has succeeded in upgrading a 5100 to the latest pfsense version. Any do's and don't's appreciated.
