I downgraded to 1.22.2 version and the shortcode button is back. The error massage is gone. I guess that because of the updated version to the newest, so the error massage came up.
So maybe you would fix the problem in the next update version.
FYI. I still use wordpress version 4.9.16, is it possible becus of old version of wordpress may effect your plugin shortcode function?
