I would like to know where is the file location to change the icons svg. Example, i would like to change the images/icons such as the home, notification, message etc to my own.
Its bit hard to change the svg, if you want you can change the svg format to normal image icon format, to change the home notif and message on jomsocial toolbar you can edit / override this file components/com_community/templates/jomsocial/layouts/toolbar/base.php
