After upgrading to 5.35.1 I am getting a memory limit reached error when loading the SMTP settings page. I am not sure if this is related but I am getting a growl error for "Failed to find key by ID or tag" and then a random string.
I have tried getting to the page with and without the CiviCRM Secret Keys set in my settings file. I have cleared the cache. My memory limit is set at an obscene 3000M.
I have this working on my dev server with the same SMTP settings. The dev server has the CiviCRM Secret Keys set. I am using;
define('CIVICRM_CRED_KEYS', '::SOME VALUE');
Any help or ideas of how to fix this are appreciated.
