Hi!

When I click on Login link, I see the following error:
"Object reference not set to an instance of an object."

I added a sub portal to my portal and logout. But now I can't login.

Is there any help about it? I really need it.

try to restart application (e.g. by editing and saving web.config file) if you have access to the database, get the details of the error from table eventlog.

I changed the web.config file but nothing happened. I found the following error in EventLog table:

Can’t you login to the new sub portal or the old one?
Can’t you login as a Host or Admin?
Here is a far shot.
Seems like one of the modules in the page is having trouble.
Did you install a new module recently?
R U trying to login from the same page all the time?
 ry opening another page, preferably a page that has minimum modules in it. For example I would try going directly to one of the admin pages (You need to know the direct address to it, since it is 4.8.4 I can't give you this) which are most likely unchanged and no new modules installed on them.
