After the full-time whistle hundreds of fans raced onto the pitch in celebration.
On Tuesday, the FA announced, external it had charged Stockport with breaching rule E21 – failing to ensure spectators do not behave in a way which is improper, offensive, violent, threatening, abusive, indecent, insulting or provocative and/or encroaching onto the pitch.
The club has until 10 October to provide a response.
