It doesn’t look like there is a bpbold theme?

From the plugin’s FAQ:
Make sure your theme’s search input field has an id=”s” and/or name=”s” as in TwentyTen and TwentyEleven. It’ll work fine then.
Sorry, the name is Boldwp.
And semms to have this as I se in chrome:
<input type=”search” class=”boldwp-search-field” placeholder=”Search …” value=”” name=”s” autocomplete=”off”>
I tested it on a local site and it seems to work as expected. Maybe there’s an incompatibility with onother plugin?

If you’re referring to the overlay version of the search input, it looks like it’ll need a CSS change to not be covered by it. I’ll bump the z-index.

a ok, thank you, maybe I found another solution 🙂
Unfortunately could not solve this.
“CSS change to not be covered by it. I’ll bump the z-index” says to me nothing 🙁
