MOSS 2007 Document Library does not allow more than 1 item

Question

I have a document library within a subsite which allows me to add only one item into it. When I try to add one more item I receive the following error.

Library can hold only one item. So please delete the existing item and upload at Microsoft.SharePoint.Library.SPRequestInternalClass.PutFile(String bstrUrl, String bstrWebRelativeUrl, Object varFile, PutFileOpt PutFileOpt, String bstrCreatedBy, String bstrModifiedBy, Int32 iCreatedByID, Int32 iModifiedByID, Object varTimeCreated, Object varTimeLastModified, Object varProperties, String bstrCheckinComment, UInt32& pdwVirusCheckStatus, String& pVirusCheckMessage) at Microsoft.SharePoint.Library.SPRequest.PutFile(String bstrUrl, String bstrWebRelativeUrl, Object varFile, PutFileOpt PutFileOpt, String bstrCreatedBy, String bstrModifiedBy, Int32 iCreatedByID, Int32 iModifiedByID, Object varTimeCreated, Object varTimeLastModified, Object varProperties, String bstrCheckinComment, UInt32& pdwVirusCheckStatus, String& pVirusCheckMessage)

The document libraries within home site and other subsites allow any number of items. Kindly let me know how to overcome this.

Thanks.

The problem was with one of our event handlers which was actually limiting the file count to one. Deactivated it and everything worked perfectly.
