APG vNext Version 3 Troubleshooting 101

This guide covers the most common issues new APG vNext v3 users encounter and how to fix them quickly.

Blank Page or Yellow Error Screen

  • Enable detailed errors in web.config by setting customErrors mode="Off" to see the actual error message.
  • Check the Windows Event Log (Application) for ASP.NET errors.
  • Verify the database connection string is correct.

Forum Loads but No Styles Applied

  • Ensure the application is set up as an IIS Application, not just a virtual directory with no app assigned.
  • Check that the App_Themes folder and its contents are readable by the IIS application pool identity.
  • Confirm the theme name in Admin Panel → Settings matches a folder in App_Themes.

Cannot Log In as Administrator

  • Verify you are using the email address you entered during setup (not the username) if "Login with email" is enabled.
  • If locked out, connect to SQL Server and run: UPDATE APG_Members SET IsLocked=0 WHERE Email='[email protected]'

File Uploads Not Working

  • The uploads folder must have write permissions for the IIS application pool account.
  • Check the maximum upload size setting in Admin Panel → Settings → Attachments.
  • IIS also has a default request size limit — increase maxAllowedContentLength in web.config if needed.
