 * Hello –
    I suspect this may have something to due with the recent upgrade to 
   WP 5.5 The admin screen is showing a repeated warning – via the Jquery Migrate
   Helper:
 * /plugins/crelly-slider/js/jquery.crellyslider.min.js: jQuery.attrFn is deprecated
 * We are running PHP 7.3
    We have the newest version of the plugin installed.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fjavascript-warning-depreciated-code%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * That deprecation error was logged on 12th December, the day before Crelly Slider
   1.4.4 was released. Hopefully it should not show up again as it should have been
   fixed.
