Hello @Balga
It seems the issue is not the template.
The issue seems to be the robots.txt file in your joomla installation and not the template itself. In order for Google to be able to render your website properly Googlebot needs access to the JavaScript, CSS, and image files that your pages use.
So the solution provided was as follows. Open your robots.txt file located in your joomla install. Edit as shown in the following image -

You simply put a hash tag in front of the css templates and images folders (The hash tag simply comments them out). Now test your site in google again and see if the issue is resolved.
