# Generic booking error on locked dates

A guest trying to complete a booking sees a generic "an error occurred" message, and the dates appear to be locked.

**Why this happens.** This error typically occurs when the dates become unavailable while the guest has the booking page open. The guest may have kept the tab open for research without refreshing it. During that time, the booking hold expired or another guest booked those dates. When the guest tries to complete the booking on dates that are now locked, the generic error message appears.

**What to do.** Refreshing the page should resolve this issue.
