Legacy version of jQuery
jQuery Migrate Helper
This plugin, called Enable jQuery Migrate Helper, is not a fix. It is a temporary solution to give your plugin and theme authors time to update.
If you get warnings, please check for updated versions of the plugin or theme that generated the warning. There will very likely be one you can install. When you have updated your plugins and themes, and there are no more warnings, please deactivate Enable jQuery Migrate Helper.
You are currently using a legacy version of jQuery. It has no support and doesn’t receive security updates. Please upgrade as soon as possible.
Also do you provide update for Slider Revolution and WPBakery Page Builder just asking though.
