I upgraded WP to the current version and when ever I enter my credentials the page simply refreshes. I read through numerous posts here on the forms and this seems to happen to people for different reasons. I have checked to make sure that wp_version is equal to my db version in wp_options. I have completely deleted the plugins folder. I even did a fresh install of wp. It's starting to drive me crazy and I've been trying to resolve this issue for a couple of days now.
I'm wondering if this might be an issue with our servers? We are self hosting and have never had problems in the past. It's an older unix server running Windows 2000. Some background info: I'm using PHP version 5.2.6 and mySQL API version 5.0.51a.
Does anyone have a suggestion?
