hello! I loaded the extension in LocalSettings.php file, when I clicked edit, Visual Editor's interface popped for one second, and asked if I will switch to VisualEditor, but I missed it and clicked on something else..I am stuck with the plain editing interface.
I tried to remove the VisualEditor from /var/lib/extensions/ and re-upload again and load LocalSettings.php again, but the notification never pops up..
any clues?
