If you need to restart iFolder services, you must stop and start Apache services:
As a root user, enter the following command at the terminal console:
/etc/init.d/apache2 stop
/etc/init.d/apache2 start
Avoid using the Apache Restart command, instead you must use Apache reload command. If any other modules using the Apache instance do not exit immediately in response to the Apache Restart command, iFolder might hang.
