Problem after installation Mobile Joomla 2.1.16

Hello! After installing Mobile Joomla 2.1.16 there was a problem on a mobile device associated with the content width on the screen. What is the reason and how to solve this problem? The screenshot images of the site on the screen before and after installing the extension attached.

@el.sergeevna , may I ask if you have a previous version of Mobile Joomla and was it working?

Please send us a temporary admin login to our email support​@​mobilejoomla.com for further investigation.
