Quick Temp fix until they figure it out try this

1. Open group.php in your dolphin root
2. Round about line 257, find
return DesignBoxContent( _t("_Group forum"), $ret, 1, $caption_item );

3. Comment it out. It should now look like this
// return DesignBoxContent( _t("_Group forum"), $ret, 1, $caption_item );

4. Well, at least it hides the Ocra link and error for me.

I hope this helped a little.
