The reason it’s appearing as just a box is because you have the accent color and the link color set the same. So the text that says Search: Type and Enter isn’t visible. If you want to keep the search box you’ll need to change either the link color or the accent color to a different color.
If you just want the box removed altogether you’ll need to add this to the custom css in the options page.
Thanks for the code for removing the search box from the header area; it overlapped my header graphics and I wanted to get rid of it. It took me a little while to figure out where to put the code snippet but by trial and error I got it. Thanks for the very good set of admin options and controls for this theme. When I get further into it and decide to keep it I will make a donation. 🙂
Glad you got it figured out. I will be adding an option for search box position as it seems it is a common question. I appreciate any and all donations.
Thank you for your support of my theme, and development.
