# Fatal error: require(): Cannot redeclare class mailtohelper

I am getting the following error message on my Joomla site:

Fatal error: require(): Cannot redeclare class mailtohelper in /home/web/public_html/joomla/components/com_content/helpers/icon.php on line 84


Any help is appreciated

• An extension is trying to redeclare a class mailtohelper. This error often occurs to me when I create new extension and forget to rename the class on the helper.php file. Try to disable latest extensions you recently installed and then enable one by one to find which one is causing the problem – Marco Jan 22 '16 at 17:03

A 3rd party extension is causing this. The mailtohelper shouldn't be invoked directly. Just use the Joomla mail object:

\$mailer = JFactory::getMailer();

• Pretty sure he's hasn't even suggested he can code. – BodgeIT Nov 22 '16 at 17:52

require ('file_path_here');


try using

require_once('file_path_here');


Whenever you need any file to be included in the current page then remember,

require() includes file that previously been included. require_once() ignore the file if it is previously been included in the same page.

try to figure out difference between include(), include_once(), require(), require_once() then use whichever is best for you.
