It was all working fine prior to upgrade. Now I am stuck and cannot upload images using message template CK Editor. Keep receiving this message when dragging picture on the window and getting an error message when using upload function. All other uploading throughout civicrm seems to works fine. Anyone had similar issues? How did you fix it please? Thanks

enter image description here
