Error messages after today's update

I ran the latest Enfold update today and got the following error messages:

jQuery Migrate Helper
Right now you are using the Enable jQuery Migrate Helper plugin to enable support for old JavaScript code that uses deprecated functions in the jQuery JavaScript library.
Please note that this is a temporary solution which will only work between WordPress 5.5.0 and 5.6.0 is, and is not meant as a permanent fix for unsupported code.

If you get warnings, you should check the theme or plugin that generated them for an update. 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.

* A script, a file, or some other piece of code is deprecated when its developers are in the process of replacing it with more modern code or removing it entirely.

Dismiss this notice.
