I am having a problem that is kind of hard for me to explain:
After I updating my hosting package to VPS I noticed that I was not able to access the dashboard of any site that I had mapped, from the my sites > site name > dashboard. It would redirect and I would have to enter mymappeddomain.com/wp-admin in the address bar to get access to my site. I didn't worry about this too much.
But then I was having trouble with simplepress and I found something saying that I should change my siteurl in settings to mymappeddomain.com instead of mymappeddomain.mydomain.com. Simplepress still was giving me an error. So I changed the home url in settings to same thing and most things were better. Then I noticed that I was having trouble with certain admin menus redirecting to login.
When I go to pages or post I get redirected to: http://mymappeddomain.com//wp-login.php?redirect_to=http%3A%2F%2Fmymappeddomain.com%2Fwp-admin%2Fedit.php%3Fpost_type%3Dpage&reauth=1 - then I can login and everything seems fine until I go to a post that I want to edit
and this I am not able to log in to at all.
I have also noticed that on my dashboard... some widgets contain nothing but the login box...
If anyone has any thoughts that would be great.
