Which operating system?
Which browser are you using?
And did you turn off all popup blockers on your computer? (Browser's blocker, all toolbar blockers such as Google toolbar, any other blockers?)
Tried uninstalling any special toolbars?
Hope this helps and let us know more.
I'm trying to get into a website but it says popup blocker was detected. I turned off the pop up blocker but it still doesn't let me get in.
