After updating my Wordpress site running on IIS7 to version 3.0.3 I tried updating the theme (LightWord) to the latest version. The theme auto upgrade feature failed so I logged into my server and tried to access the directory of the theme via the file system(C:\websites\wordpress_root\wp-content\themes\lightword). To my surprise I was told I did not have access to the directory. I tried viewing the ACL list for the theme folder but again was denied access. I access the Windows 2008 machine (which is actually a VPS) via RDP but I log in as an administrator. Shouldn't I have I have access to ALL files on the server? Has anyone else run into this issue?
It looks like even the Administrators group was removed from that folder. It's rare for an app to remove that, but it does occur. The LightWord theme installer must have a bug in it.
You can get it back again by taking ownership of the folder. You can do that from the same security tab as you update the permission. Take ownership, save out, and then add the administrators group back again.
