Hey guys I'm still very new to opnsense.
After updating the system I can't access the WAN/LAN interface settings anymore.
Here is the error I get:
"Fatal error: Cannot create references to/from string offsets nor overloaded objects in /usr/local/www/interfaces.php on line 76 "
Thanks for the help.
Fixed via https://github.com/opnsense/core/issues/128 -- expected to be included in 15.1.8.4 on Tuesday.
