If you want to hide the information icon from your calendar (the small white i in a blue circle) then this is hidden automatically when you install a JEvents Club Members plugin, any plugin at all that requires a membership. If you are not using a Club Plugin then you can do the following:
Simply add the following to JEvents CPanel -> Custom CSS
img.jev_help {display:none;}
(Note: Custom CSS feature was added to JEvents 3.0.13 and upwards)
A more complex method is to create a template override file called defaultinformation.php (defaultinformation16.php in Joomla 2.5) and place this in the folder :
templates/YOUR TEMPLATE/html/com_jevents/helpers/
This file should consist of this content:
<?php defined('_JEXEC') or die('Restricted access'); function DefaultInformation($view){ return; }
