Why has my website header disappeared on secondary pages?

[SalfordSilver]

Hey, I have just had some issues when trying to replace code which had suddenly stopped working (not due to editing code either). I deleted all the code i was trying to replace, and replaced it, which then seemed to mess up my header and footer. 

I replaced all theme.scss.liquid, header and footer code from the original Brooklyn theme file. This seemed to fix my issue, however now when i click on any other page which is not the first page of the website, the header to access the other pages has disappeared.

Please help!

Hello, @SalfordSilver 

Welcome to the Shopify community!
and Thanks for your Good question.

1. Go to Online Store->Theme->Edit code
2. Asset->/theme.scss.liquid->paste below code at the bottom of the file.

.hero__header {
position: relative;
    opacity: 1;
}

Since midnight I have went round and round with 5 different employees, none of which helped me. My header disappeared in shopify, the menu everything. It was there, then it was gone. I have been disrespected all night, I am tired, today is a big day for my site and I have no header. No one has a solution.

Hey @SalfordSilver.

I appreciate that you have added the link to your store as that is super helpful. I'm sorry to hear about the trouble you are facing, let's see what we can do to help.

If you recently have made a coding change on your theme that caused the Header to no longer display. You can roll back to an older version of your theme. If you would like to revert the changes, you will need to navigate to Online Store > Actions > Edit Code. I took a screenshot from my test store to show you the section I am referring to:

Once you are looking at the coding of the theme, you can then select Older versions of your theme to have the changes reverted to an earlier date. If you noticed a purple dot next to the files, that means changes have been made to the template and you should be able to revert the changes made.

Let me know if that fixes the issue.
