Unable to login to web gui (Fatal error: Unsupported operand types)

[RimBlock]

Hi,

I have just logged in to my PFSense server and selected [Status] –> [Show DHCP leases] when I lost all connectivity (my PC network port went to 'not connected').

Since then, if I try to connect to the web GUI, after I supply the username and password i get the following error…

Fatal error: Unsupported operand types in /usr/local/www/index.php on line 309 Call Stack: 0.0000 227592 1\. {main}() /usr/local/www/index.php:0 PHP ERROR: Type: 1, File: /usr/local/www/index.php, Line: 309, Message: Unsupported operand types

I have tried rebooting the server but no change.

The error occurs in Chrome and in MS Edge.

Any ideas on how I can get back in to my PFSense GUI ?.
