Website error

Hi, When users go to my website, Blender101.com, they get the following error: Fatal error: Allowed memory size of 62914560 bytes exhausted (tried to allocate 7 bytes) in /homepages/38/d606854309/htdocs/clickandbuilds/Blender101/wp-content/themes/upfront/library/theme/class_upfront_virtual_region.php on line 279. I get a similar error when attempting to access my Dashboard.
Do you know how I might solve this?
Thanks for your help.
