I only in the near past up to date my WordPress, theme, and plugins, and am now getting these two errors on prime of the homepage and pages web page.
Deprecated: wp_make_content_images_responsive is deprecated since
model 5.5.0! Use wp_filter_content_tags() as an alternative. in
/var/www/html/wp-includes/capabilities.php on line 4773
and the pages web page,
Discover: register_rest_route was known as incorrectly. The REST API route
definition for pum/v1/analytics is lacking the required
permission_callback argument. For REST API routes which can be meant to
be public, use __return_true because the permission callback. Please see
