[Theme: Arjuna X] Not compatible with Viper007bon "Viper Quicktag Video plugin"

Hello.

When activated, the plugin to embed video “Viper’s Video Quicktags” is not wirking : buttons are ok on new post editor but not results when clicking on it.
Then I activate another theme and it works so problem is with Arjuna :/

Any idea ?
