I've running CiviCRM 4.7.31 on Wordpress 4.9.6. When selecting Events -> Find Participants, I get the following warnings and a blank screen:

Strict Standards: Static function CRM_Core_Task::permissionedTaskTitles() should not be abstract in .../wp-content/plugins/civicrm/civicrm/CRM/Core/Task.php on line 132

Warning: Cannot modify header information - headers already sent by (output started at .../wp-content/plugins/civicrm/civicrm/CRM/Core/Task.php:132) in .../wp-content/plugins/civicrm/civicrm/CRM/Utils/System/Base.php on line 926

Furthermore, when I go into the Events Dashboard, I get the following each time:

Standards: Static function CRM_Core_Task::permissionedTaskTitles() should not be abstract in .../wp-content/plugins/civicrm/civicrm/CRM/Core/Task.php on line 132

Is this a bug or an issue with my setup possibly?

This has been recorded and fixed in later version of CiviCRM. You can either apply patch manually to 4.7.31 or upgrade CiviCRM to 5.2.1.
