Responsive layout problems caused by third party plugin

Hi,

Here is the link to my site:
https://seowho.co.il/boldial/

For some reason the site is not responsive. I’ve tested it on iPhone 4 and Galaxy S3 and the same issues appears. As you can see there is a blue color gap on the side, as well as some text sliding out and the floating contact form on the side is too big etc..

The settings on the theme options are set to responsive. I hope you can help me with this as it is extremely important.

Thank you so much
