I would suggest to compare your dev and production web.config. Looks like one or more handlers are missing

Hi!

Thanks for the tip, that was it!

On the server I found this:

<configuration>
  <system.webServer>
    <handlers>
      <add name="wildcard" path="*" verb="*" type="EPiServer.Web.StaticFileHandler, EPiServer.Framework.AspNet" />
    </handlers>
  </system.webServer>
</configuration>

That one was not in my web.config on dev.

I can see that you have used this in you post about securing a location:

Securing a Static Folder | Episerver Developer Community

And that make sense. Any guess why the original developer har put this in the "main" system.WebServer?

Thanks!

Hi!

Without that line no css is loading, static files, and with that line the plugin does not load. Any ideas why?

Looks like you need this in your production web.config

        <add name="PageHandlerFactory-Integrated-4.0" path="*.aspx" verb="GET,HEAD,POST,DEBUG" type="System.Web.UI.PageHandlerFactory" preCondition="integratedMode,runtimeVersionv4.0" /> 

  <location path="episerver">/<system.webServer>/<handlers>

Almost, I had to add this:

<location path="modules/MyPluginFolder">
    <system.webServer>
      <handlers>
        <clear />
        <add name="PageHandlerFactory-Integrated-4.0" path="*.aspx" verb="GET,HEAD,POST,DEBUG" type="System.Web.UI.PageHandlerFactory" preCondition="integratedMode,runtimeVersionv4.0" />
      </handlers>
    </system.webServer>
  </location>

Thanks for your help!
