I just recently moved a wordpress installation from my MAMP local server to a web server.
Everything is working fine except when in wp-admin i'm getting this error.
Warning: realpath() [function.realpath]: Unable to access /my-path/wp-admin/admin/admin.php in /my-path/wp-includes/functions.php on line 1963
The function that is throwing the error is path_is_absolute().
The wierd thing is it looks like wordpress is trying to look for an admin folder inside of wp-admin, which there isn't.
