Sure have. I guess I should've taken the clue that no one has been able to fix it for other people...posts going back to last November with this problem keep noting "Hey - you've got one too many slashes! Fix that!"
As helpful as that may seem, those of us having this trouble have only changed the parts of the code in wp-config.php that you're told to change. I don't know php, and my only thought is that ABSPATH is being misdefined somehow.
So - for someone who knows php - how do you get a script to print out the value of a string? Then I can see if the problem is ABSPATH.
Btw, this is the one changed I've tried so far:
thinking to get rid of that final /
but no, that didn't work.
So heck if I know.
