Hi @duongcuong96,

Thanks for your comments! I had both Smart Slider 3 Pro dev team, as well as AX Social Stream dev team looking into this problem.

This is what I get when php error logging is on:

[16-Dec-2020 14:10:55 UTC] PHP Fatal error:  Uncaught Error: Call to undefined method GuzzleHttp\Utils::chooseHandler() in /usr/home/mysitename/public_html/wp/wp-content/plugins/ax-social-stream/library/guzzlehttp/guzzle/src/functions.php:61

This problem could be reproduced by Smart Slider 3 dev team, and AX Social Stream dev team advised me as follows:

The problem is where our plugin is using Guzzle library and the BackWPup plugin is also using the same library but with a different version. We are using the latest version of Guzzle library in our plugin. You need to contact the author of the BackWPup plugin and ask them to update the Guzzle library to the latest version.

I hope this helps. Are you able to get the info you need from this?
