PHP Warning: class 'MainWP_Security' not found

I am receiving the following message in my error log:

“PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘MainWP_Security’ not found in”… “wp-includes/class-wp-hook.php on line 287”

Probably just an FYI rather than a question.

Hi Richard,
thanks for reaching out.
Can you tell me do you get this on your Dashboard or child site side?

These PHP warnings are found both on the hosting and the client website error logs.

Hi Richard,

Can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Status --> Server, on the top right of the page.

Hi RIchard,

thanks for getting back to me.

Report looks good.

The only thing that I noticed is that you are still using the Broken Links Checker extension that has been retired over a year ago. Can you please try to disable it and see if that helps? I just want to be sure that this old code is not causing this.
