Can’t save changes in the Admin Section

Each time I try to save a change on any Admin section I get kicked out to the login page, and then when I try to re-login I am taken into a redirection loop that always takes me to the login page. Sometimes the changes are saved but most aren’t. I can go back into the admin area if I click on the Admin link of my blog or if I click Edit on a post. The redirection link looks like this: https://glg.iphix.net/wp-login.php?redirect_to=http%3A%2F%2Fglg.iphix.net%2Fglg%2Fwp-admin%2Fwidgets.php.

I would really appreciate any help I can get.
