Fatal error: Cannot redeclare crypt data
If the following error is received after updating pfSense to 2.1.2-RELEASE:
Fatal error: Cannot redeclare crypt_data() (previously declared in /etc/inc/crypt.inc:35) in /etc/inc/crypt_acb.php on line 43
It may be fixed by using the console/ssh shell, or Diagnostics > Command to run:
rm /etc/inc/crypt_acb.php /usr/local/pkg/autoconfig*
Make sure there are no spaces between the g and *. After running that command, reboot the firewall.
If packages were installed installed, they may require a reinstall by going to Diagnostics > Backup/restore and clicking Reinstall all packages.
Afterward, go to System > Packages. If no packages show installed, then first reinstall the AutoConfigBackup package and then any other packages that were missing.
