I use stable version of WP 2, I added the question here to this topic because it is what I think caused prob.
Anyway I solved it by editing file wp-includes/functions.php and change row 1785 from:
$screenshot = glob(“$theme_root/$stylesheet/screenshot.*”);
to
$screenshot = globX(“$theme_root/$stylesheet/screenshot.*”);
I had the same problem and did what OzzyQ suggested. Installation went ok but after it when I log in as admin I see the following errors:
Warning: glob() has been disabled for security reasons in /DISK2/WWW/….
Please can someone help?
