It has no been confirmed when the production, which is due to run to 9 November 2013, will reopen.
A press representative said the press night will likely be rescheduled until "the week commencing 23 September."
The play, adapted by Joanna Murray-Smith from Ingmar Bergman's 1970s Swedish TV series, follows Johan and Marianne from happily married couple to warring contenders in divorce and beyond.

The cast also features Shane Attwooll, Aislinn Sands and Melanie Jessop.
