getting kicked out upon login

[Hawk7173]

When members go to the forum index page and login, the welcome window comes up as it should, but then it goes back to the forum index page as if they have not logged in. However if one clicks on the forum button, it will then show as being logged in.

The only thing that I have done in the last few days was to redirect domain names to the forum index page rather than the front page. That and upload a couple of mods.

I disabled the mods and the problems still exist. should I uninstall the mods and then check it before reinstalling them?

could it be something that has to do with the redirection of the domain names?

I did notice that the front page did the same thing from the very beginning.

Any help is greatly appreciated.
