    Dear Mailgun dev,

    Since the last update we get the following notice in all our updated sites/shops.

    Warning: Undefined global variable $_SESSION in?/xxxxx/wp-content/plugins/mailgun/includes/admin.php?on line?340

    Warning: Trying to access array offset on value of type null in?/xxxxx/plugins/mailgun/includes/admin.php?on line?340

    WP_DEBUG is switched off, this notice only appears on the WP backend, on top of every page.

    We use version: 1.9.8 for all sites that have the display of this warning.

  • I have the same issue and submitted it on the Mailgun support site.

    They told me to go on the Settings page and change “Use HTTP API” to No.

    This did not solve the warning.

    I just updated to version 1.9.9 and am no longer receiving this PHP warning.

    Thanks Mailgun!
