Civi 4.7.14 Wordpress 4.7.5 Using Mosaico (the original one)
All's been going fine for months and months.. suddenly the tracking has stopped working. The emails are being received..just not being reported.
I tried this suggestion: CiviMail tracking opens stopped working after upgrade to 4.7.x
ie cut and paste this link img src="https://yoursite.org/sites/all/modules/civicrm/extern/open.php?q=91954565" width='1' height='1' alt='' border='0'
but got a black screen- no error message- which I guess is what I'm supposed to get?
thanks for any suggestions
