Blank page

Hello,

Since several days, my start page at http://www.digistef.com is blank.
After activating the debug function I get these error messages on screen:
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; sidebar_generator has a deprecated constructor in /home/digistefcom/public_html/wp-content/themes/unicon/framework/inc/sidebar-generator.php on line 29

Seems like a problem with the unicon theme.

Any idea how to fix this?
