Hi I want to delete header category

Hello,

This could be a plugin conflict so please disable all plugins except visual composer, clear cache and reset cdn files if you use it. Please also check any custom code you might have added to the theme panel or the theme files. If you use a child theme, please switch to the main theme to make sure it does not affect the proper functionality of the theme.

The theme scroll bar is a very very thin line that will not take up much of the screen but the css seems to be replaced with the bulky default scroll bar.

Thank you!
