hi,
how do you build for production?
The package Volo.Abp.AspNetCore.Mvc.UI.Theme.Shared is on NuGet .
It should find it from https://www.nuget.org/packages/Volo.Abp.AspNetCore.Mvc.UI.Theme.Shared/
Check your NuGet.Config. The order of the package sources are important.
It should be first "nuget.org" then "ABP Commercial NuGet Source"
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
<add key="ABP Commercial NuGet Source" value="https://nuget.abp.io/*************/v3/index.json" />
</packageSources>
</configuration>
Don't forget to replace your private API Key (/*************/)
this issue has been fixed in v2.4 (coming on April 3, 2020)
hi,
we'll try to reproduce and get back to you
Firefox has an optional feature that allows the browser to trust root authorities in the Windows certificate store. To activate this feature, you must enable the setting in your browser.
about:config into the Firefox address bar.

security.enterprise_roots.enabled 
security.enterprise_roots.enabled window, look to the right side of the screen. If the value is false, double-click on it to set it as true.try signing in from http://localhost:4200/account/login then you'll see the administrator menu.
I think the problem is there's no Login link.
