Joomla! Template JD MedicX - Item Support

I'm trying to install a GMap plugin, I tried with 2 different (Phoca Maps, and other) but none of them worked. Is there a blocker or something like that? what could be happening, I've already used those plugins before and never had any issue.
Thanks.
I've fixed it with the code generated on gmap, that's ok.
I am dealing with another problem now, I have the template installed on this temporary server: http://c1460507.ferozo.com - The idea is that the home shows with this structure: http://c1460507.ferozo.com/index.php/es/home
Home is set as 'Home' Page. It is a menu of 'Blank content' type, anyway it is shown with another structure, not the one you see on the second link.
How can I set, o what should I change in order that when you access the home, when you arrive to the page it keeps the structure that you see on the second link?
I need to fix this. The client is getting anxious. When I create a blank page it is working fine if you access from the menu, but if you set the page as home page, it shows an article in middle. I had to install a pageblank_component because I couldn't find an option for that as on the demo site.
Hello, I need to change a background on hero-section for mobile, how can I do that? I tried changing the css but I think is scss/less generated file, but I don't know where to change it or customize.
Thanks!
I've tried that but doesn't work. On this link to googledrive I upload a screenshot, the site is corvusweb, a temporary domain. Here is a screenshot of the desktop version. https://drive.google.com/file/d/1illq42P8sCZ7x8Aao2t1XCn9C-c5ljR4/view?usp=sharing
Meanwhile on the mobile version, the image of the background doesn't appear. That's why I want to make it appear but smaller.
I've added a custom.css file with the code on the template/css folder, I also added a customization.css and include it on the index.php, but neither of those solutions works. Here is how it's being shown on the mobile version:

Please I need to fix this issue, because after that I have another customization that are similar, and I need to include custom codes that modifies the mobile behaviour.
The site is on this url: http://c1460507.ferozo.com, let me know what do you need in order to help me. Thanks in advance.
I've tried that but keeps showing the same:

What I want to do, is show the same image that in desktop but smaller, like this mockup.
