This thread is resolved. Here is a description of the problem and solution.
How can I get rid of the error messages on my site?
It looks like these are just warning and not actual errors. If you disable the debug display, this should resolve the issue. Please disable the debug display by editing the following lines in wp-config.php:
define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false );
