* Hello,
* I just updated the plugin and am now getting the following errors:
* 1) We were unable to decode the JSON response from the Mandrill API: 504 Gateway Time-out
The server didn’t respond in time.
* 2) We were unable to decode the JSON response from the Mandrill API:
500 Internal Server Error
500 Internal Server Error
nginx/1.4.6 (
Ubuntu)
* 3) API call to messages/send failed: Empty reply from server
* 4) We were unable to decode the JSON response from the Mandrill API: 504 Gateway Time-out
The server didn’t respond in time.
* Any idea how I can resolve these issues?
