Yes, that is the search bar in the header I want replaced.
You should be able to login now, I didn't realize I had wordfences security login options heavily restricted.
I don't have FTP setup, but when you login and see the dashboard you will see something called “File manager”. It has a search feature built in to search for files and edit. I've located the searchform.php files using the builtin search feature with file manager. Just not sure exactly what I'm suppose to do from here to get the header search replaced.
