I downloaded, unzipped, uploaded and set permissions on ubb threads, but when I ran the install.php I couldn't go beyond step 1. All of my directories passed the permissions test except three: Sessions, Template/Compile and Cache all failed. I uploaded them all the same, I used CHMOD all the same on them, and yet they failed. I set permissions again, but still they failed. I deleted them from my server and then reuploaded them to my server and set the permissions and they still failed.

In the FTP program, I can see that they have the proper permission designations, but no matter what when I hit "check again" I get the same three listed as failed. I'm stumped as to why only those three directories fail. Any ideas?
