Hi Tygra and Falkzilm,
Both your problems are caused by floating elements.
Tygra, your problem can solved by placing the following line in your theme's "footer.php" file, after "
<!-- end of col-380 fit -->" and before your slideshow's PHP snippet:
<div style="clear: both;"></div>
Falkzilm, you can solve your problem the same way by placing the line of HTML code above right before where you have placed your slideshow. That may be a little harder in your case.
You could also go into your theme's folder and open the "style.css" file. Look for the following block of CSS code, starting at line 2396:
margin: 20px 0;
font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif;
Your problem should be solved after removing the line with "float: left;" and saving the file.
