You can fix this by editing the class.widgets.php file. just do a search inside the file for “search across all blogs” and you’ll find where it’s plugging the text in to output, and you can change it to whatever you want.
Never mind, I figured it out!
For anyone who wants to do this, go into resources->business-hours.css and change:
.business_hours_has_exception td.business_hours_table_open, .business_hours_has_exception td.business_hours_table_close, .business_hours_has_exception td.business_hours_table_closed {
text-decoration : strikethrough;
}
to
.business_hours_has_exception td.business_hours_table_open, .business_hours_has_exception td.business_hours_table_close, .business_hours_has_exception td.business_hours_table_closed {
display : none;
}
