Fatal Error

Hi dear support,

when I click on the code snipets plugin I get the following error:

Fatal error: 

Fatal error: Uncaught Error: Call to undefined method CSP_ShippingManager::get_instance()
in /home/ashwagan/domains/holistic-med.ch/public_html/wp-content/plugins/code-snippets/php/snippet-ops.php(469) : eval()’d code on line 3

Thank you very much in advance.
