Gillingham took advantage of Port Vale's defeat at Northampton to stretch their lead at the top of League Two to five points.
While Port Vale stumbled to a 2-0 defeat at Sixfields, Gillingham were ruthless at Kingsmeadow where they eked out a 1-0 victory over AFC Wimbledon.
Romain Vincelot netted the visitors' goal in the 23rd minute, a 20-yard strike by the midfielder on loan from Brighton.
Northampton's Alex Nicholls scored but suffered a suspected broken leg in the process against Port Vale.
He netted his side's opener in the 20th minute but was fouled at the same time by Vale's John McCombe, who was sent off for his challenge. Nicholls left the pitch in an ambulance.
Northampton doubled their lead in the 43rd minute when Louis Moult converted Adebayo Akinfenwa's pass.
Cheltenham's bright start to the season continued with a 3-0 home victory over Exeter. Lawson D'Ath opened the scoring after 55 minutes and Keith Lowe added goals in the 62nd and 87th minutes to make it a comfortable success, lifting Cheltenham up a place to third.
The Robins climbed ahead of Fleetwood who were held to a goalless draw at Rochdale, whose Ashley Grimes had the best chance of their match but failed to convert a 49th-minute penalty.
Fifth-placed Bradford had Ricky Ravenhill sent off at Burton and Calvin Zola's 80th-minute header condemned the Bantams to a 1-0 away defeat.
Rotherham climbed one place to sixth thanks to a 1-0 home success against Plymouth, Kieran Agard's 73rd-minute close-range finish proving decisive.
Torquay nudged up to seventh, the last play-off place, as Danny Stevens' 30th-minute strike delivered a 1-0 home success at the expense of Morecambe.
Accrington, with Leam Richardson in caretaker charge after Paul Cook's defection to Chesterfield, put the week's upheaval behind them to beat Bristol Rovers 1-0 with a 79th-minute goal from Padraig Amond.
And Cook saw his new team lose at home to bottom-of-the-table Barnet, Mark Byrne's 90th-minute penalty a rude awakening for the incoming Spireites manager.
Wycombe endured a miserable derby with Oxford at Adams Park, their visitors leaving with a 3-1 win.
James Constable and Tom Craddock put Oxford 2-0 in front, Joel Grant pulled one back from the penalty spot, and Johnny Mullins restored the two-goal cushion in the 62nd minute.
York were held 0-0 at Southend, while Dagenham & Redbridge and Aldershot also played out a goalless stalemate.
