I hope you are well today and thank you for your question.
I can see you are using an older version of the theme on your shared website so could you please update it to the below latest version as described here https://support.shufflehound.com/blog/2018/01/24/updating-theme/
Please login to access this file
I did the update to 5.1.1 and cleared the cache, it still doesnt work. What can I do?
It is working fine on other pages of your website as below.
It means this is only your home page specific issue.
Would you mind if I log in to your site and do quick troubleshooting? If this is ok then could you please temporarily create an admin user account and share the account login details privately by adding them in the box having text “Enter your private content here (only you and forum moderators will be able to see it)”?
I used the box underneath “Enter your private content here (only you and forum moderators will be able to see it)” to send you everything you need.
Solution for this topic
I logged into your website and found out that the sticky header is working fine on the home page If I deactivate the YellowPencil plugin.
It seems there is a conflict with the CSS code generated by the YellowPencil plugin so please remove the CSS code.
You can reset the Yellow Pencil editor as described on the below pages.
