Frequently Asked Questions
As a security precaution, CGI and PHP scripts run with different user credentials than you do when you edit your files. Although the CGI/PHP user has significantly fewer privileges overall, it is possible to create a situation where an application creates files or directories that you do not have permission to access or remove via FTP or ssh. This typically happens if an application's umask is set incorrectly; the resulting files or directories will be owned by the "web" user and will not be group or world writable. (Correct umasks are 0 or 002, depending on the expected group ownership. A umask of 0 should work for most web applications, and does not compromise security on our system the way it does on some shared hosts.)
If you get stuck with web-owned files you can't access or delete, you can regain control using the "Repossess Files" action on the Site Information panel for the affected site. However, if you find yourself doing this on a regular basis, that tends to indicate your site's permissions aren't set properly.
