Make sure to remove all unnecessary code which is wrapped around your slider code. Open your post in Text/HTML editor and remove everything and leave only your actual slider shortcode like this:
[image-carousel twbs="3"]
To understand what is Text/HTML editor I am talking about, please make sure to read this article.
To get rid of title and date you can add this code to Theme Options - Other - Custom CSS
I am a bit puzzled why you have attempted to modify theme like this. You could have used regular static page on front page and that would avoid most other mistakes you have made so far in code.
When you commented out code from sidebar.php you left → in it. Personally I would leave sidebar file with opening and closing php tags and the rest I would remove completely. Other solution would be to get rid of <?php get_sidebar(); ?> from all template files, so sidebar.php would not be loaded at all.
Make sure to enable Jetpack Carousel module. You already have Jetpack installed and enabled but you also need to enable this module to make images to work the same way as in our theme demo.
thank you for the speed with which you respond to my questions. Your theme is fantastic! I’ll rate it and put a good opinion about your topic and about you in wordpress.
Appeared to me two questions though …
1st - In the carousel, title and date appear again, having already placed the same code in Theme-Options - Other
