Conflict with "UpdraftPlus Backup/Restore" plugin

I get the following error/explanation only when “Random Featured Image” is activated.

Do you have a JavaScript or jQuery error?
UpdraftPlus’s admin page is highly interactive. This interactivity is achieved in the usual way – using the JavaScript programming language, and the jQuery JavaScript library.

Sometimes, other plugins may have JavaScript and/or jQuery errors which cause the UpdraftPlus settings page to fail to display properly.

When this happens, it is always the fault of the other plugin/theme – because they should not be loading JavaScript at all on UpdraftPlus’s settings page. The fact that their JavaScript is causing a conflict just makes it worse; but, they should be loading it only on their own settings page.

Please assist. I can only perform backups when I deactivate this plugin.
