Comments.Text: Can you edit the above civi version - I think you mean 5.35.1 not 3.35.1
  
  Also - can you check if you have flexmailer enabled under extensions

ThreadText: # Civimail - loss of opt-out, unsubcribe & forwarding
  
  (Asked by: username_0 on 2021-04-13)
  
  I have a Drupal 7.79 and a Joomla 3.9.25 site on the same server, both running Civi 5.35.1 and both with loss of unsubscribe, opt-out and forwarding capability.
  
  Flexmailer is enabled on both sites.
  
  In the CiviErrors extension output (which I don't understand) I see the lines below (note the occurence of &).
  
  [entryURL] => https://SITE-ONE/index.php?q=civicrm/mailing/unsubscribe&reset=1&jid=9099&qid=1380011&h=7d6e80ef654067bb

  The emails sent and received do not contain munged URL's and the 'access CiviMail subscribe/unsubscribe pages' permissions appear to be set correctly.
