Re: System.NullReferenceException

Do you have any data in the mp_Sites table?

If not try typing a space into your web.config file and save it to recyle the application so that it will try and create the default data for you.

Hope it helps.

Re: System.NullReferenceException


I see one line :
1, '', 'mojoPortal', 'subblue', 'mojotonguesmall.gif', '', 1, 0, 0, 0, 0, 'mojoPortal, C#, ASP.NET, mono, linux', 'A site of interest to .NET developers wanting to deploy ASP.NET on Linux', '<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" />', '<meta Portal="mojoPortal" Version="2.0" />', 1, 0, 0, 'PageNameWithDotASPX', 'normal', 0, 1, 1, 0, 1, '', 389, '', 'CN'

Any ideas?

Re: System.NullReferenceException

Try deleting the row from mp_Sites and then type a space in your web.config and save to recyle the app then try the page again in the browser.

Or even better to drop all tables then run the script to recreate them, then modify web.config so it recycles

Re: System.NullReferenceException

Great!

Not sure what happened, something must have gone wrong with the initial creation of data.

Glad you're up and running!

Cheers,

Joe
