Support » Plugin: Post SMTP Mailer/Email Log » admin-ajax.php error version 2.0.20 – learndash quiz

  • Resolved neilgee


    Plugin conflict with Post SMTP and LearnDash – when calculating a quiz in LearnDash a server 500 error is generated from /wp-admin/admin-ajax.php

    Disabling Post SMTP or rolling back version to 2.0.19 fixes issue.
