Comments.Text: You could start by clearing out templates_c folder, clear caches and also rerun the Smart Group cache link from Manage Groups ie /civicrm/group?reset=1&update_smart_groups=1

Title: CiviMail - 'No recipients': nothing added to table civicrm_mailing_recipients
ThreadText: # CiviMail - 'No recipients': nothing added to table civicrm_mailing_recipients
  
  (Asked by: username_0 on 2018-03-25)
  
  I have migrated an existing installation to a new server followed by an upgrade to 4.7.31.
  
  When creating a new mailing I keep getting "No recipients" **when I add groups or smartgroups**.
  If I add recipients of past *mailings*, it works as expected (I get xx recipients).
  
  In the database
  - the table civicrm\_mailing\_group gets a new record (so OK)
  - the table **civicrm\_mailing\_recipients** does not get new records added.
  
  So the problem seems to be related to populating the civicrm\_mailing\_recipients table. How do I debug/solve this?
