Upgrading to the latest version – list_files error

upgrade from what version?

2.6 to 2.6.2

i would do this:

delete all of the files inside wp-admin/includes/

reupload the 2.6.2 files that belong in there.

Done still the same error..

Any one got any ideas?

do you have wp download manager version 1.0 and activated that plugin?

please change list_files to other name on downloadmanager.php (not download-manager.php)

I solved that problem for my blog. You can see my problems regarding this problem here
