the site working on machine. after few days started getting above error without code change. going through log files got above error. changed 

   227     template_preprocess(&$variables);

by

   227     template_preprocess($variables);

and site started work. not able figure out exact reason issue same code worked , creating issue.

been cms(content management system) have created new contents , added taxonomy. there no change done code.

the php fatal error occurs because server running php 5.4 using php 5.3 or earlier version (check version in admin/reports/status in drupal). if did not happen on server until possible host updated version running.

the solution make sure have updated drupal , modules , report bug module's maintainer.
