Fatal error-Cannot create references to/from string offsets in /usr/local/www/firewall_nat_1to1.php

[Thoufiq]

Hi i am running pfsense FreeBSD 11.2-RELEASE-p3 (2.4.4-RELEASE (amd64)). I came across an issue today that i wanted to delete a list of 1:1 NAT policies so i selected four 1:1 NAT mappings and clicked on Delete button which is red in colour. As soon as i clicked the delete button i got
"Fatal error: Uncaught Error: Cannot create references to/from string offsets in /usr/local/www/firewall_nat_1to1.php:42 Stack trace: #0 {main} thrown in /usr/local/www/firewall_nat_1to1.php on line 42 PHP ERROR: Type: 1, File: /usr/local/www/firewall_nat_1to1.php, Line: 42, Message: Uncaught Error: Cannot create references to/from string offsets in /usr/local/www/firewall_nat_1to1.php:42 Stack trace: #0 {main} thrown" error and in the dashboard i got a crash report
