yes, i agree, it's a warning, not an error, but no, it's not my eyesight, i've reloaded everything 4 or 5 times now, and each time there is no warning at all from the original install, as my hosts have 1-click install that works absolutely fine - the configure.php is in fact set as 600 after the install, and is still 600 after i try to upload all the STS files. This warning only appears after i upload the STS RC2 files, and even then, only the files that overwrite existing files in the includes directory.
