Using Joomla! Administrator

Go to Administrator → Global Configuration → Server.

Using the UNIX Shell

Note The find command assumes that it should start from the current directory. To be safe, go to your public_html directory and specify a path as the first argument. Some shells, such as bash on Apple OS X, must have a path specified in the find command.

find . -type f -exec chmod 644 {} \;
find . -type d -exec chmod 755 {} \;
chmod 707 images
chmod 707 images/stories
chown apache:apache cache

Notes

1. Test all third-party extensions after changing permissions.
2. You may need to reset write permissions to install more extensions.
