after first setup config I can't see website folder in HTDOCS

I do wonder why does it happen to the original one though, it's just a little strange that even with new copies on that original machine, things won't work out correctly.

Angela, how can we find out? The world is a big mess in total, so it's impossible to find explanation for everything ;=)

the only suggestion I can give you is to keep an eye on that machine in similar situations
maybe the filesystem is broken on your harddisk etc. many many reasons
who knows?
