WooCommerce was updated to version 2.6.7, from version 2.6.6. Changelog:

• Fix – Use FLOOR and CEIL to get price filter values. Fixes the issue where max price is capped at 99.
• Fix – Hide “Sales this month” information from Dashboard widget for users that don’t have view_woocommerce_reports capability.
• Fix – Remove notices only once on cart so subsequent notices do not remove older notices.
• Tweak – Improve credit card fields for better mobile experience.
