Chester and one of their experienced players have been fined after misconduct at Edgar Street last season.
The match officials for the home game against Chester last season
Experienced midfielder Declan Weeks has been suspended for the first two games of the new season after an FA misconduct panel looked into the incident.
While it doesn't go into detail, the FA said that in or around the 72nd minute of the match, which ended in a 1-1 draw, the club "failed to ensure that its players did not behave in a way which is improper".
Under the heading "surrounding a match official", the FA said the club admitted the charge and were fined £850.
As for Weeks, under the heading "incident outside the jurisdictions of match officials but reported to the Football Association, it said he would be handed a two-match ban and fined £150.
It was after he admitted breaching FA rule E3.1: "It is alleged that upon conclusion of the fixture, following the incident for which he was dismissed, his language and/or behaviour was abusive and/or insulting and/or improper and/or questioned the integrity of the match official."
Referee Jonathan Maskrey sent Weeks off after the final whistle, picking up a second yellow card.
It was a "dissent offence of some sort", according to Chester boss Calum McIntyre. Weeks had already served a one-game suspension for the red but after the misconduct charge also missed the opening game of this season against Spennymoor Town. He will also miss next Saturday's game at the Deva against Brackley Town.
"Although disappointed with the decision to suspend Declan for a further two matches – given he had already served a suspension – and misgivings both player and club held over the evidence before the panel, we respect the outcome, and look forward to seeing Declan back in action soon," the club said on Saturday.
McIntyre said after the game in February: "Fundamentally, that's frustrating for us [Weeks' sending off].
"I have an opinion on it. Without witnessing the conversation, I just think it's really important if Deccers said what the referee said and that's a yellow card, I don't understand how there haven't been 22 yellow cards.
"I don't understand how me and the opposition manager have been cautioned, I don't understand how everyone involved in the game hasn't because it's an emotional game and people are passionate."
In a tense affair, McIntyre's side took the lead in the first half after Elliott Whitehouse put Hereford keeper Curtis Pond under pressure after he failed to firmly hold onto a corner ball. But the hosts pulled themselves back level thanks to an Andy Williams penalty.
