Hello. I think we have the same problem, but it seems to me that you have been able to fix it and moved on. Please tell me if I am right.
You have tried to install website baker and when you have reached step 2 in
http://help.websitebaker.org/pages/en/basic-docu/installation/wb-installer.php you got "not writeable” in each post.
You have then changed permission into 777
(World-writeable file permissions (777)” should never be on for a real live site. Turning this option on enables anyone to access all your site's folders and files, and make any changes they'd like. This option is used only by programmers and developers, during testing and troubleshooting.) You have then installed website baker as normal and afterwards changed these permissions back to 755 manually with your FTP-program? Or have I got this wrong? Does this work?
