Can anyone help me fix a recurring error in WP. I get the following message overlaying my Optin form:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /home/content/31/9647731/html/pre-diabetes fitness/wp-includes/plugin.php on line 525
Does anyone know how to fix this problem? I am using the Platform Theme.
Contact me at [email protected]. I am not a techie and this problem is causing a lot of issues.
My WP page where this error is occurring is:

Thanks in advance for any assistance,
Owen
