[Serusers] Confirm fault

[Håkan]

When I "klick" on the link in the mail I got in return after I "subscrib"
from the webb.
..../user_interface/index.php  I get this messages:

"400 Table 'aliases' not found in memory, use save("aliases") or
lookup("aliases") in the configuration script first"

400 = bad request

Why is that? How can I get it right? I do not understand what to do with
"aliases".
