Interfering with Visual Editor

Sorry I can’t reproduce this problem it works fine when I tested it https://i.imgur.com/Cq2ntyI.png

I’m gonna try to disable some more plugins.
When I activate wp-polls I can’t visual-edit existing pages or new ones.

It was a misconfiguration on wp-config.php.

WP_CONTENT_URL pointing to a different environment (we have developing,testing and production environment).
