Hi, my error log, I see the following notices:

PHP Deprecated: Function Redux::setHelpTab is deprecated since version Redux 4.3! Use Redux::set_help_tab( $opt_name, $tab ) instead.

PHP Deprecated: Function Redux::setHelpSidebar is deprecated since version Redux 4.3! Use Redux::set_help_sidebar( $opt_name, $content ) instead.

PHP Notice: Array to string conversion in …/wp-includes/kses.php on line 1685

PHP Warning: strlen() expects parameter 1 to be string, array given in …/wp-includes/class-wp-block-parser.php on line 489

Any insights on how to address them? Thanks!
