Hi,

After updating title in JL Mine Pro configuration on Joomla 3.9.26, I have now this error on landing page

Warning: require_once(/home/amisabba/www/libraries/joomla/document/html/renderer/head.php): failed to open stream: No such file or directory in /home/amisabba/www/templates/jl_mine_pro/error.php on line 28

Fatal error: require_once(): Failed opening required ‘/home/amisabba/www/libraries/joomla/document/html/renderer/head.php’ (include_path=’.:/usr/local/php7.3/lib/php’) in /home/amisabba/www/templates/jl_mine_pro/error.php on line 28

I try fix it in error.php with
if (!class_exists(‘JDocumentRendererHead’)) {
$head = JPATH_LIBRARIES . ‘/joomla/document/html/renderer/head.php’;
if (file_exists($head)) {
require_once($head);
}
}

but now

variable @hover_color is undefined: failed at border: 1px solid @hover_color; /home/amisabba/www/templates/jl_mine_pro/less/presets.less on line 58

Can you help me ?

Regards
