THANK YOU SO MUCH FOR YOUR HELP! The Soledad Theme is awesome. I am sorry to give you so many headaches! However, this morning I implemented the Soledad search function (see it installed on Widget footer column #2) and when you use it, it breaks the site! If you click inside the search field, or "enter", it throws up this error alert:
