    Hi @theaziz22

    Hope you're doing well today!

    I tested Pro Sites in my install, but I was unable to replicate the issue, so, can be some plugin conflict.

    However, I think this is a simple PHP warnings and most of the time it doesn't affect any functionality of site.

    Do you have WP_DEBUG set to true in your wp-config.php file?

    Cheers, Luís
