Edit: Object reference not set to an instance of an object

Hi all

I was editing my page at home location and used the "edit" to go and edit some text. When Update button is pressed, some error appears and the log show's this:

Re: Edit: Object reference not set to an instance of an object

Hi Adelino,

Here is my best guess of the problem.

You edit your site sometimes from home and sometimes from work. At work you changed your username or email address on your user account. When you got home you were still logged in as the old user name because you had a persistent cookie because you check the remember me box when you login. So when you go to edit it sees from your cookies that you are authenticated and you are in a role with edit permissions but when you save content it cannot find your site user because your cookie no longer matches an existing site user (because you changed it at work) so it gets a null user object and causes this error. 

The solution is to click the logout link then login again, or else clear your browser cookies then login again. Then you will be able to edit again without errors.

Hope it helps,

Joe

Re: Edit: Object reference not set to an instance of an object

Thank you.

I logged with admin in IE on the virtual machine and it worked. I usually use my laptop to work on remote desktop and Firefox to view the pages. And it was probably that the problem.

I'm testing mojoportal to see if it is really an alternative to dotnetnuke and joomla. Those other cms have great looks and features too, but mojo is amazingly simple. It has lot's of themes too.

Anyway, you all have done an excellent job!

Thanks

Adelino
