Glastonbury ticket sales have been delayed by two weeks after some music fans reported issues with their registration, organisers have said.
The official announcement came just hours before the first batch of tickets for the 2024 festival were due to go on sale at 6pm today for the coach package.
The general admission tickets were expected to go live on Sunday morning.
Tickets will now be available to buy on Thursday 16 November for tickets plus coach and on Sunday 19 November for general admission.
A Glastonbury statement said the postponement was to ensure "everyone who would like to buy a ticket is registered and therefore eligible to purchase one".
It said some people hoping to buy tickets for next year's event have found out after Monday's registration deadline that "they are no longer registered, despite believing they were".
"Out of fairness to those individuals, we will be re-opening the window for registration at 12 noon on Monday 6 November. It will remain open until 5pm on Monday 13 November."
Glastonbury apologised for the late change.
The festival says registration is essential to prevent touting as each ticket has the photograph of the registered ticket holder with security checks in place before entering.
Tickets are non-transferable.
