Thanks. That resolved the problem. Is this something which will need to stay there permanently?
I have updated to 4.0.2, which helped because now I can see the image upload button on the category page.
But I am still unable to assign images to categories, because when I press the “Upload” button nothing happens. Instead, a Javascript error is displayed in the console.
I have created an account for you to log in and troubleshoot … refer private information field.
I must be missing a plugin? My categories screen doesn’t have the ability to add an image.
