komento-2.0.6.static.min.js error on HWDMediashare page when inspecting with Chrome

I had installed both Komento Pro and HWDmediashare on my Joomla website, and integrated them to allow commenting on videos.

Today I inspected my HWDmediashare page with Chrome browser, I got following error:

Uncaught TypeError: Cannot read property 'init' of undefined                   komento-2.0.6.static.min.js:680

See attached screenshot.

You can use your Chrome browser to inspect my HWDMediashare page at:

https://www.joomlagate.com/index.php?option=com_hwdmediashare&view=mediaitem&id=33:xampp-add-ftp-server&Itemid=500&category_id=55

My system info:

PHP 5.5.33
Joomla 3.4.8
HWDMediashare 2.0.5
Komento Pro 2.0.6

Could you please tell me what is wrong on my website, and how to fix this?

Thank you.
