Ckeditor image upload working, but saying it doesn't (using ckfinder)

Question

I'm using ckeditor on my website (PHP,HTML,JavaScript), and I'd like my users to be able to upload image through the editor, but when I try to do it, the image appears like it's supposed to, then I get an error message in a pop-up saying the image couldn't be uploaded, when I click on the pop-up the image disappear. The weird thing is that the image does get uploaded successfully in the right folder...

Anyone got any idea on how I could fix this?

I don't really know what part of my code I should share, so feel free to ask me.

Answer 1

The problem was inside the script to create the editor:

ClassicEditor.create( document.querySelector( '#editor' ), {
  ckfinder: {
        uploadUrl: '/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images'
    },

it seems that ckfinder doesn't automatically return a response to let the editor know the file successfully uploaded, so i had to change it to this:

ClassicEditor.create( document.querySelector( '#editor' ), {
  ckfinder: {
        uploadUrl: '/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images&responseType=json'
    },

My bad for not reading the docs correctly
