I want to have a domain-based multiple-site in Spanish and English. The site is on shared hosting so my site is in a folder.

I'm using the full sources, published the site locally, cleaned up the published files and ftp'd to the server. Everything runs fine:

System Information:
mojoPortal Version 2.4.0.3 MSSQL
Operating System Microsoft Windows NT 6.0.6002 Service Pack 2
ASP.NET Info v4.0.30319 Running in Partial Trust

I set the domains up and setup the second site and both domains resolve correctly to their respective site.

Then, to force each site to use Spanish and English I followed the instructions at http://www.mojoportal.com/forcing-a-specific-language
and I added these four lines to the web.config (ensuring they didn't conflict with any existing appsettings):

  <add key="UseRelatedSiteMode" value="true">
  <add key="UseCultureOverride" value="true">
  <add key="site1culture" value="en-US">
   <add key="site2culture" value="es-ES">
    
This results in the following error:
    
Server Error in '/eng' Application.
Value cannot be null.
Parameter name: connectionString

There is nothing else in the Mojoportal log. After testing it seems it is the UseCultureOverride appsetting that is causing the error.

I'm completely stumped! Any ideas?

I can't believe I missed that

Thanks Joe!
