Fix "serach" misspelling on widget in Writerstrap theme

I am using the Writerstrap theme. Inside the search box is the misspelling “serach”. I’ve been looking online for a suggestion about how to fix it with no luck. I can’t affect it from the Dashboard. I was also told to look at widgets.php. That file lists the search widget, but there’s no place to alter it. I also went to the theme page and posted a question, but it doesn’t look like there’s been any activity on it in months.

Any help would be appreciated. Someone else must have noticed this and fixed it already.
