since the last update the shortcode forhas a bug.
On the position in the webpage where the tab-shortcode is located the Plugin "Code Insert" inserts the things that belong to the end of the article.
So the shortcode produces a "end of article" kind of marker that the "Code Insert" Plugin needs to see where the article ends.
Please fix it, because it destroys functionality of my webpage.
(Has to temporarely take out tabs shortcodes)
