I come back to you because I have a big problem, I lost the button that allows me to insert an image.
I realized it on the version 4 of Joomla. But it's the same thing on version 3.10.2.
On version 4 of joomla, I wanted to access the parameter of the editor, impossible, it is a white page that loads.
I thought it was an extension, I searched, but it is the white page.
