I just noticed that my search widget is gone. It is designed by CSS to display at the top of the page on the right side, directly across from my blog's title and description.
After WordPress updated the widget page a few weeks ago, I had to rework my CSS for the search field and button because WP had added a number to the class ("search" had become "search2"). This was apparently a result of them adding a way to save previously used widgets for later use. I don't know if this is related to the current issue or not, but thought it might be worth mentioning.
The blog I need help with is inrepair.net.
