I am sorry, I got it fixed by reading your tutorial. I got that error because the version of vertex framework i was having is 4. and i had to update it to 4.1 by deleting the theme wp-include and admin in control panel.
Now i have 2 problems
1. my S5 Image Slider.I have it in the custom 3 position. I uploaded images in the media and i linked it with images but doesnt seem to work. Custom 4 is in the correct positionhttp://demo.qfautomation.com/
