Error: E_COMPILE_ERROR

I was notified by wordpress that I am receiving an error:

An error of type E_COMPILE_ERROR was caused in line 21 of the file /www/wp-content/plugins/maxbuttons/assets/integrations/shortcake/shortcake.php. Error message: require_once(): Failed opening required ‘class-field-maxbutton.php’ (include_path=’.:/usr/share/php:/www/wp-content/pear’)

Any recommendations?
