How to remove Archive Category: X From DropDown Categories

It would most likely be in the archive.php file in your theme.

How would I access this file.

Via FTP or the theme editor in the admin panel. Be sure to make a backup copy before you change anything.

Actually, much of what appears on the Archive page can be styled using Graphene’s custom CSS feature or a child theme. There is no need to hack into the theme’s core files. (Such hacks will be overridden at the next update.)

Try this tutorial for a way to alter archive pages via CSS:

Thanks for the article. However, it doesn’t tell me how to remove the archive box, just change the color of it which I already know how to do. If anyone has a custom css that I can add to my site would be great! Please help!

Do you mean the actual text “Category Archive: For Whatever Category”?

If you want to hide that text, you can add this to custom CSS:

.archive h1.page-title {display:none;}

If you want to change the text to say something else, you will need a custom function. There are instructions for that on the Graphene forum:

Thanks! The custom CSS tip worked.
