Most likely cause is that the switchport is receiving BPDU's via the AP, making it think there is a loop in the network. Is the Access Point the only device on this port?
If not, I suggest that you try and disconnect the AP to check if the port goes back to forwarding mode.
If the access points are in bridge-mode the loop may be caused by the radio overlap. You should reconfigure your access points for this. The best way to do this is to configure them on different radio channels. Preferrably use channel 1, 6 and 11 and then once more channel 1. Make sure that both AP's on channel 1 do not overlap.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
