With the Moodle version 3.3.1+ (Build : 240812017) the Grid Format works perfectly, but when I have updated to Moodle version 3.4 and after re-installing the Grid Format with 3.4.0.1 (2017111800) the following message appears : "Cannot convert uploaded image to displayed image"
In addition this problem doesn't appear in all courses, but when the curse show the grid format we lost all uploaded images and the grid is empty.
Any reason / solution for this ?
Thanks in advance
