Cisco Wireless :: AP1242 - Privileged Exec Password Works For Telnet But Not Web Interface

I recently configured a Cisco AP 1242, software version 12.4, via the web interface using the default Cisco credentials. At that time I setup an administrator account with read/write access and changed the Cisco to a read only access. Now went I attempt to login to the web interface it won't accept the administrator password. It will except the administrator password in a telnet session however. So via the telnet session I setup another user with privileged exec level access and that wont work on the web interface either. The Login box keeps coming back requesting a password. Strangely enough, I can login to the web Interface using admin username, with the Cisco password; but I can't do anything, and I also can't view everything. I've tried the following:

I've turned on SSH and created a certificate in the AP, but the login box continues to pop on the https://url.I've attempted to setup a user with a non-encrypted password, but have been unsuccessful.I've tried a different browser - login box continues to pop.I've made sure the web interface is activated in the API've tried a differnet computerI've tried disabling password-encryption service. Reset the enable password , I've successfully setup other 1240 APs but must have done something wrong on this one.
