Joomla recently released J3.8. Unfortunately they removed over 300 files in the update (in preparation for the forthcoming Joomla 4.x) that our Gantry 4 templates relied upon. We will be updating all G4 templates as soon as we can to apply the fix but in the mean time you can apply this fix yourself too.
1. Look in the templates/TEMPLATENAME/ folder
2. Open three files error.php, offline.php and comingsoon.php
3. Find this line in each:
require_once(JPATH_LIBRARIES.'/joomla/document/html/renderer/head.php');
and replace with:
if (!class_exists('JDocumentRendererHead')) {
require_once(JPATH_LIBRARIES.'/joomla/document/html/renderer/head.php');
}
