As I’ve answered on our own support forum, the errors are not caused by Mantra but by HTML errors in your page.

The errors postet on your forum are “div” and “p” errors. On my “text editor” in wordpress there is neiter.
Here is an example of code wich is not working:
[mantra-column width="1/4"]<a title="Erik Faber" href="http://www.gbfestivalen.no/artister/erikfaber/">Erik Faber</a>
[caption id="attachment_263" align="alignnone" width="150"]<a href="http://www.gbfestivalen.no/artister/erikfaber/"><img class="size-full wp-image-263" alt="" src="http://www.gbfestivalen.no/wp-content/uploads/2013/04/erikfaber150.jpg" width="150" height="150" /></a> <a href="http://twitter.com/share?text=Erik%20Faber%20til%20GBfestivalen%202013&url=http://www.gbfestivalen.no/artister/erikfaber/"><img style="padding: 5px;" alt="twitter-button" src="http://www.gbfestivalen.no/wp-content/uploads/2013/04/twitter-button1.png" width="30" height="30" border="0" /></a><a href="http://www.facebook.com/sharer.php?u=http://www.gbfestivalen.no/artister/erikfaber/"><img style="padding: 5px;" alt="facebook-like-icon" src="http://www.gbfestivalen.no/wp-content/uploads/2013/04/facebook-like-icon1.png" width="30" height="30" border="0" /></a>[/caption]
[/mantra-column
WordPress generates paragraphs for newlines.
Try typing in that text with absolutely no spaces / newlines, like
[mantra-column width="1/4"]<a title="Erik Faber" href="http://www.gbfestivalen.no/artister/erikfaber/">Erik Faber</a>[caption id="attachment_263" align="alignnone" width="150"]<a href="http://www.gbfestivalen.no/artister/erikfaber/"><img class="size-full wp-image-263" alt="" src="http://www.gbfestivalen.no/wp-content/uploads/2013/04/erikfaber150.jpg" width="150" height="150" /></a> <a href="http://twitter.com/share?text=Erik%20Faber%20til%20GBfestivalen%202013&url=http://www.gbfestivalen.no/artister/erikfaber/"><img style="padding: 5px;" alt="twitter-button" src="http://www.gbfestivalen.no/wp-content/uploads/2013/04/twitter-button1.png" width="30" height="30" border="0" /></a><a href="http://www.facebook.com/sharer.php?u=http://www.gbfestivalen.no/artister/erikfaber/"><img style="padding: 5px;" alt="facebook-like-icon" src="http://www.gbfestivalen.no/wp-content/uploads/2013/04/facebook-like-icon1.png" width="30" height="30" border="0" /></a>[/caption][/mantra-column]
