Organisers of Ed Sheeran's Dublin shows say they are putting "additional measures in place" for tomorrow and Saturday's performances.
It's after thousands of fans that turned up to see him in Phoenix Park on Wednesday ended up stuck in a "bottle neck" and complained that they didn't have a clear view of the stage.
A number of callers to 98FM's Dublin Talks complained that they were "stuck down the back", "left standing out with the food trucks" or "couldn't get back out to the toilet".
Aiken Promotions explained that "movement of people through the large gap between two banks of seats worked well all night until Ed took to the stage when we had approximately 5k people still to come in."
"When Ed went on stage those people who were in the concessions /toilet area and those still entering came in through the gap but did not move on to take a place in the designated standing area, they just stopped inside the gap to watch the show."
Organisers explained that area was not meant to be a viewing area, and "was designed to facilitate movement".
"This meant the people behind those who had stopped were unable to get into the viewing area and likewise some people were unable to get back out to the toilets for a time."
Aiken Promotions says it's meeting with Gardai and security teams to review the layout and put additional measures in place to prevent it happening again.
There were no reports of any injuries, and Ed Sheeran fans heading along to his final two Dublin shows are being encouraged to get there on time and to follow stewards directions.
