Instead, I got:
"jQuery Migrate Helper — Warnings encountered
This page generated the following warnings:
hidden link.......org.uk/wp-content/plugins/cred-frontend-editor/library/toolset/cred/embedded/assets/common/js/mvc.js: jQuery.browser is deprecated hidden link.......org.uk/wp-content/plugins/types-access/vendor/toolset/toolset-common/res/js/toolset-settings.js: jQuery.fn.load() is deprecated
Please make sure you are using the latest version of all of your plugins, and your theme. If you are, you may want to ask the developers of the code mentioned in the warnings for an update. "
The notices were just deprecation notices and didn't affect functionality, the plugin revealed the deprecation notices.
In any case, we released hotfixes to the key plugins yesterday evening to resolve these notices as well as a PHP notice which appeared with WordPress 5.5.
If after updating you still see any issues, please let me know, thanks.
