Different to what he mentioned using Shell Access, you can set your file and directory permissions using this wonderful plugin : Site Scan

Site Scan

Site Scan is a standalone script providing the ability to recursively scan directories and their files to check permissions compared to the recommended settings of 755 (directories) and 644 (files).


I simply unzipped the content of Site Scan to my root folder and went to mysite.con/sitescan.php and choose to fix file and directory permissions.



I am a passionate PHP user with a love for Open Source systems. With a few years of programming these technologies, I am fortunate to be able to share my thoughts. Joomla and WordPress are my favorite systems to develop. That's enough for now.
