Hi,
It appears that you still have not activated the premium add-ons.
The last digit in a 4-part version number is the number of installed add-ons. So 2.16.2.0 means 0 add-ons installed.
The the most common values are:
.0 – No add-ons installed
.1 – A single add-on installed
.24 – All add-ons installed (full Premium)
Please reconnect the plugin to our licence server by entering your username and password in the “Premium/Extensions” tab.
“Gateway Timeout
The gateway did not receive a timely response from the upstream server or application.”
HTTP 504 error – explained here: https://www.checkupdown.com/status/E504.html – means that your web hosting company deploys a proxy in front of your web server, and that this proxy is having a problem. The only real way to investigate it is to forward the information to the web hosting company, and to ask them what the cause of the error is.
Regards,
Bryle
