Uncaught Error: Tests could not be loaded

When I click the icon on the toolbar, I get the following error:

Uncaught Error: Tests could not be loaded
    at Object.error (plugin.js?t=I63C:48)
    at u (jquery-3.3.1.min.js?ver=4.9.8:2)
    at Object.fireWith [as rejectWith] (jquery-3.3.1.min.js?ver=4.9.8:2)
    at k (jquery-3.3.1.min.js?ver=4.9.8:2)
    at XMLHttpRequest.<anonymous> (jquery-3.3.1.min.js?ver=4.9.8:2)

And when I click it again, I get:

    at t._selectIssue (plugin.js?t=I63C:18)

As you see I have jQuery 3.3.1 and balloonpanel plugin, But I get these errors.

How to solve that?

I too am getting this error. For some reason, the URL is adding an extra "/" when trying to pull the tests file. The file being requested in the browser is:

/ckeditor/4.7.1/plugins/a11ychecker/libs/quail//tests.json

Note the // before tests.json on the end.

This issue is a little bit old but, do we have any update?
