Ok i finally worked out what it meant, i have installed it and it is coming up in the install list now but when i install it, it is only partly coming up then has the following error:
Fatal error: Smarty error: [in buttons/button.tpl line 12]: [plugin] modifier 'amp' is not implemented (core.load_plugins.php, line 11
in /home/c/h/charmedgifts/public_html/Smarty-2.6.3/Smarty.class.php on line 1082
What does this mean please?
