Main Slider disappears

Hi, thanks for providing this wonderful theme.

It looks all good for me and fulfills all my requirements, exactly the same way I needed. However, I’m having an issue with the theme, when I’m trying to make any changes in any page, the main slider disappears. This happened to me when I first installed the theme but removing and adding it worked for me, now again facing the same issue. Even I’m not sure that this happens due to my changes or there is something wrong within the theme. Also, I didn’t find any error on the chrome console. To view the screenshot open this link http://prntscr.com/lvuyzl

Any help would be highly appreciated.

Thanks and Regards,
Ahmad Raza
