Hi all.  I'm running DNN core 4.3.7 and just upgraded the Events module from 3.3.0 to 3.3.7.  I like the improvements, especially the skinning changes.  Here's the problem...on a calendar in month view, I click an event.  It pops up the detail view.  Then when I click "Export Event to Desktop Event", I receive an undefined error page.  Below I've pasted the unhelpful error page, and then the Log Viewer details are pasted below that.

I'm not a programmer, so I have no idea where to begin.  Any ideas?

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

Server Error in '/sysadmin/desktopmodules/Events' Application.

I'm not sure this corresponds to the error above, but it's my best guess:

Thanks for the reply, favance.  I'm still a little lost, however.  I'm running DNN 4.3.7 core, and I can't find any reference to Compression in the Host Settings when logged on as Host.  Questions:

1.  Are you implying that upgrading to DNN core 4.4.1 or greater will eliminate the problem?

2.  Is there a way to control Compression that's external to the UI in core 4.3.7 (a text config file, perhaps)?

3.  Is it possible that Compression is set outside of my control?  This site is hosted at webhost4life.com.

4.  Where do I find an "Excluded Paths" entry?  Is that in a config file, or in the DNN UI somewhere?  I can't find it.

I got my host to increase logging.  Now when I attempt to open the .vcs file, I receive this error:

Parser Error Message: The code subdirectory '/sysadmin/desktopmodules/Events/App_Code/Reports/' does not exist.

Source Error:

Line 99:       -->
Line 100:      <codeSubDirectories>
Line 101:        <add directoryName="Reports" />
Line 102:        <add directoryName="Survey" />
Line 103:      </codeSubDirectories>

1.  Is this a bug that surfaces because of the Events 3.3.7/Core 4.3.7 combination?

2.  Is there any way to work around this by editing web.config?

3.  What are the chances that this problem would go away if I upgraded to Core 4.4.1 or greater?
