	1- With FTP access:

		c) <a href='tiki-install.php$install_link'>Execute the Tiki installer again</a> (Once you have executed these commands, this message will disappear!)

	or

	2- With shell (SSH) access, you can run the command below.

		a) Run setup.sh and follow the instructions:
			\$ bash
			\$ cd $docroot
			\$ sh setup.sh

		The script will offer you options depending on your server configuration.

		b) <a href='tiki-install.php$install_link'>Execute the Tiki installer again</a> (Once you have executed these commands, this message will disappear!)
