Banned member not showing in ban list

[marcicj]

I have SMF version 1.1.13.  I have a member who cannot log into the forum.  I am able to log in using their name and password that they provided but when they do it says that they have been banned from the forum.

I looked in the error log at the times they tried to log in and I can see the ban message however I can not find their username, email, or IP address in the ban list.  Also they are saying that the IP I am getting in the error log with their username is not their IP.  They are not using a proxy server. 

I would appreciate any guidance you all can provide.
Thank you.

Try checking the smf_ban_items table in SQL. See if their username, hostname, or IP is in any of the rows there.

Did you also try checking the Ban Log? NOT the Error Log.
