[vchkpw] qmailadmin strange problem

[Martínlistas]

Hi. I have installed qmailadin... was working great, till i changed the
server time... afeter that, if I try to create a new pop account, qmailadmin
just give me "Internal server error...."
I reinstalled qmailadmin, after not finding what it was wrong. So, has
anybody a clue of what can be wrong? Qmail is workng OK, vpopmail too.
