METHOD_EXISTS(): ARGUMENT #1 ($OBJECT_OR_CLASS) MUST BE OF TYPE OBJECT|STRING, N

Hello,

I am receiving this error message on Petcare template - "METHOD_EXISTS(): ARGUMENT #1 ($OBJECT_OR_CLASS) MUST BE OF TYPE OBJECT|STRING, NULL GIVEN"

The error shows up when I enable "Coming Soon" plugin, nothing appears on the page.

I don't believe it's the Coming Soon plugin because I also use this plugin on two other sites and they are working fine. So I figure it must be the template.

My site is not published yet but if you can help me with the error I appreciate it.

Thx

still waiting for HELP

I cannot access my webpage and I've identified it as Unite Revolution Slider. Can you tell me if there is something wrong with this code - when I return to 7.4php then "Coming Soon" works. But, when I use PHP 8.0 I receive the error message. So I have reverted back to 7.4php - Coming soon works.. but I can't login to my website where Unite Revolution slider is the home page.

Or researching Joomla forum Or this code actually line 70 - a 3rd party extension

/**
*
* add some meta box
* return metabox handle
*/
public static function addMetaBox($title,$content = null, $customDrawFunction = null,$location="post"){

$box = array();
$box["title"] = $title;
$box["location"] = $location;
$box["content"] = $content;
$box["draw_function"] = $customDrawFunction;

70 self::$arrMetaBoxes[] = $box;
}

I No longer need your help. I fixed it
