Removing it has fixed similar reported issues.  Let us know if it does not work.  🙂 

Fixed, upgraded to PHP 8.1, and upgraded boards. 

Whatever that old code was it's no longer an issue.  Thank,s for the assistance.

You will want to check your conf_global.php file and remove every mention of IPB_Firewall. This not a product we make and is evidence your hosting was compromised quite some time ago. 

OK.  Removing all instances of that.  This doesn't appear to be a hosting compromise.  All these subroutines are commented with "Invision Power Board" comments and versions that are VERY old.  I believe this is before it was rebranded Invision Community, and somehow the code survived all the upgrades.

OK.  This has been moved from a previous hosting service and upgraded multiple times on my current host with no issues.  I did not realize IPB_Firewall was not part of the original Invision.  Removing.  Hopefully that's the only major issue.

I have been trying for a while to upgrade my server to PHP 8.1.  Every time I enable it, I get the following errors:

Error: Call to undefined function create_function() (0)
#0 /var/www/<website>/forums/conf_global.php(338): IPB_Firewall::_calculateChecksums()
#1 /var/www/<website>/forums/conf_global.php(310): IPB_Firewall::_doSecurityChecks()
#2 /var/www/<website>/forums/conf_global.php(542): IPB_Firewall::run()
#3 /var/www/<website>/forums/system/Dispatcher/Dispatcher.php(69): require('...')
#4 /var/www/<website>/forums/admin/index.php(13): IPS\_Dispatcher::i()
#5 {main}

I have no plugins installed.  I have attempted every purge to make sure no plugins are installed.  I switched to a default no-frills theme with no modifications.  Nothing helps.  This PHP 8.x requirement is killing me given your "vanilla" version of Invision is not working with it.

Please help.
