Latest WP Update issue

I recently ran the Wp auto update for the latest version of WP for two websites themontagemagazine.com and newportbeachmagazine.com during the install the page bounced to a new page telling me

“No Results Found – The page you requested could not be found. Try refining your search, or use the navigation above to locate the post.”

I can no longer login to access the admin panel for either site. I tried replacing the wp-logn.phop file, but no luck.

Any help is appreciated.
