A Suffolk theatre was forced to cancel a show just two weeks after being reopened following a refurbishment.
A fault closes the Theatre Royal two weeks after it reopens
A fault with the lights in the auditorium at the Theatre Royal in Bury St Edmunds caused Monday's performance of Bouncers to be cancelled.
Technical staff solved the problem in time for Tuesday's performance.
The Grade I-listed Georgian theatre has recently undergone a £5m two-year restoration project which was completed earlier this month.
The problem - believed to have stemmed from the automatic switching equipment - was discovered as theatre-goers arrived for the performance.
The 290 theatre-goers who had tickets for the show have been offered seats for another showing of Bouncers or a full refund.
The theatre's artistic director Colin Blumenau said: "It's inevitable that when you do as much work to a building as we have recently undertaken that there will be unforeseen technical issues that arise with the systems that have been put in place.
"We were duty bound to cancel the performance so as not to risk the safety of any member of the public."
