M_Boats: Problem using search interface

Hi, I'm not sure who to write to, but the search interface on the Montgomery boats lists seems to be brokenhttps://mailman.xmission.com/lurker/list/montgomery_boats.en.html If you pick a topic and try to view it, an error comes up Lurker - failed to render page: Cannot open database snapshot (Permission denied): The configured database 'dbdir' in the config file could not be opened. Typically this means that it is not readable by the user which the cgi is invoked as. We suggest making dbdir and all files in it readable by everyone since you are serving them on a website anyways. Any Ideas on who to contact?  Anyone else have this trouble?
