Adding to this thread, this is the error I am now seeing
/opt/zammad/vendor/bundle/ruby/3.1.0/gems/bootsnap-1.16.0/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:32:in `require': /lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /opt/zammad/vendor/bundle/ruby/3.1.0/gems/eventmachine-1.2.7/lib/rubyeventmachine.so) - /opt/zammad/vendor/bundle/ruby/3.1.0/gems/eventmachine-1.2.7/lib/rubyeventmachine.so (LoadError)
Seems I was able to resolve this error with installing some other missing required packages, now it loads but when I load my page it is just a blank dark screen. I get the zammad logo in the middle when it first loads then just goes blank.
