Every time I visit the site, I get an alert stating: "Error: 550 Failed to change directory." Is it just me, or is this a problem I should alert the site admin about? And what does it mean?

Make sure you come in on this URL:
http://mysettopbox.tv/phpBB2

I meant when I visit http://www.knoppmyth.net/, then I get that message. I had read the link title and mistakenly thought it was the same as where the BB is.

That's some other site.

http://www.knoppmyth.net/ resolves just fine for me, is it a link on that page that produces the error? Don't use the Forum link however, as there is the "double-login issue" as described in http://mysettopbox.tv/phpBB2/viewtopic.php?t=14938

Sorry to protract this, but it looks the same to me as http://mysettopbox.tv/ - and I get the message there too. Are they not the same site from two different domain names? They both link to this BB and have 'Basics', 'Forum', 'Knoppmyth' & 'Links' for links on the left.

The link in my last post was bad. Seems a comma became part of the link and shouldn't have.

Looks the same to me too. I have always used mysettopbox.tv, I don't know if Cecil & Co. operate knoppmyth.net (seems to be the same) or not, but I didn't receive any error on any of the links on the home page.

They look the same her too. However NSlookup implies they may be running on different hosts.

There are running on two different hosts. The only think KnoppMyth.Net is used for is FTP.

Indeed, there are three separate hosts. The web page/forum, the wiki, and the ftp site.
