problem on the site with JavaScript or jQuery

I tried to make a backup with the UpdraftPlus Backup / Restore plugin and this message appeared to me;

Warning: If you can still read these words after the page finishes loading then there is a problem on the site with JavaScript or jQuery

As you can see in this image, https://prntscr.com/t1604y

I followed the instructions on this page https://updraftplus.com/do-you-have-a-javascript-or-jquery-error/

Deactivate your plugin https://prntscr.com/t162w1 and everything was fixed, the warning was removed https://prntscr.com/t163bd

I await comments to proceed to buy your Pro version

Thank you,
