I am trying to expand my knowledge, and for 'backend' programming I use ASP.NET. I am trying to make a very simple CMS, and currenty Im on creating a blog post with just a title and topic. Works good, sends data to database, and on, lets say blog.aspx it shows data. But when I used ASP.NET 'LoginView', where I set up that if a user is anonymous, he only sees '?'. While if a user is logged in he will be able to publish a post. After that, it does not work. Just does not. When I click on a button to send the data, it shows error 'Object reference not set to an instance of an object.'.

I wouuld really appreciate any help with ASP.NET, its really giving me problems.
Should I just give up on it and move to PHP/MySQL?

ASP.NET operates just like desktop .NET so giving up seems silly.

Please post your code where the exception is happening and paste the entire error message.

I will post the code whn Im on my laptop. I believe the problem is in tge loginview? When it is not there, ot works, but when I add it to loginview so only logged in users can see it, it gives me the error. I have posted 3 images which I thought might helo.
