In the latter part of the 1960s the club dropped for a long time into the provincial leagues, however in the early 1990s it managed to climb back into Promotion.

The club never managed to regain promotion into third level and eventually it even dropped into the provincial leagues again in 1958.

From 1961 until 1967 the team spent a few seasons in the promotion division again, but then sunk deep into the provincial leagues for many years.

In 2022–23, Cappellen secure promotion to Belgian National Division 1 after defeating KV Mechelen II narrowly 1–0 with a goal in minute 27 Idriss Diawara on final day in Matchweek 34 on 14 May 2023.
