Comment (by praem90):

 PHP can't serialize closure directly. We can use
 [https://github.com/opis/closure] package for this support.

 So, it recommended to use something like below may help to fix your
 problem.
 {{{#!php
 <?php
 register_activation_hook(WPMP_BASE_FILE_NAME, array($initialize_service,
 'activate'))
 }}}
