Attempting to install ZenArmor. Getting PHP Errors

[haymak3r]

Greetings,

Running I believe the latest version OPNsense 26.7.8.
This is a test firewall that I have been messing with in the hopes that I can replace my sophos UTM home firewall.

I am trying to install zenarmor. I've got the plugins installed, and see zenarmor in the left pane. I click on that, and try to go through the wizard, which looks different now than your documentation.

I get past the license page, and get to DB settings. Though I see the errors popping too, but the wizard seems to just hang. I see in the bottom a red message stating Error 200. I have attached a screenshot.

In the logs I see hundreds of these lines:

Im not sure if this is a php issue on the box, or some issue with zenarmor itself? This IS running in a vm, but not sure how that could be an issue.

I am new to this software, and I DID search, but didn't really get any results pertaining to zenarmor and php.

Thanks!
