Hi,

I'm having trouble with a plugin: Images are not loading, and the loading spinner never disappears.

When I go to Plugins -> Product Ribbons -> Ribbon Images, no images are loaded.

There is an exception in the console.

...admin/ProductRibbonsAdmin/RibbonPicturesList 500 (Internal Server Error)

Uncaught ReferenceError: display_kendoui_grid_error is not defined
    at init.error (AddDeleteProductRibbonPicture:30:1783)
    at init.trigger (kendo.web.min.js:11:6329)
    at init.error (kendo.web.min.js:13:15754)
    at Object.i [as error] (jquery-1.10.2.min.js:4:6426)

    at k (jquery-1.10.2.min.js:6:14283)
    at XMLHttpRequest.r (jquery-1.10.2.min.js:6:18646)

The ribbons themselves work correctly and appear on products, so the issue seems to be isolated to the image loading. Could you please advise on what might be causing this?
