hello
I want to remove my hexagon image in footer what am I Should to do?

It's not part of the normal module in position bottom1 so I found the easiest way was to go in and delete the actual image itself - /templates/sj_hexagon/images/bg/title-mod.png

So what I did was create a new image with the background colour (#43474d) and uploaded that in it's place - like the attached example.
