We have been running moodle for about a year with no problem. Today, when I called moodle I received the following error:
Parse error: parse error in /xx/www/xx/moodle/lib/smarty/Smarty.class.php on line 1313
Fatal error: Cannot instantiate non-existent class: smarty in /xx/www/xx/moodle/lib/setup.php on line 105
There has been no changes to Moodle or operating system according to the system administrator. Can somebody please help as the work of our campus is halted and I cannot undertand what is wrong?
