PHP Errors Found

Hello,

In a recent query monitor scan we found multiple php errors in your plugin. Activating Query Monitor I’m seeing some PHP errors that could be slowing things down in wp-admin, especially because they appear to be running always in the WP admin – specifically background processes from the “mphb-mailchimp” plugin.

Here is a screenshot https://snipboard.io/idB32t.jpg What can be done to clean these up?

Thank You,

Michael
