Apache broke on me (unstable)

["Pim Bliek | PingWings" <bliekp@pingwings.nl>]

Hi all,

I have apache running fine on my unstable box for months now. I am
hosting some test websites (which are important for my business and for
my friends business, so I am f*cked...see below ;)) for myself and for a
friend. I do this in $HOME/public_html directories.

Since this afternoon I cannot access these public_html dirs anymore. The
normal docroot in /var/www is still working. The public_html dir gives
this error when requested:

Forbidden
You don't have permission to access /~username on this server.

Apache/1.3.27 Ben-SSL/1.48 Server at somewhere.in.the.world Port 443


Here is the part of my httpd.conf:

#
# UserDir: The name of the directory which is appended onto a user's
home
# directory if a ~user request is received.
#
<IfModule mod_userdir.c>
    UserDir public_html
</IfModule>

#
# Control access to UserDir directories.  The following is an example
# for a site where these directories are restricted to read-only.
#
<Directory /home/*/public_html>
    AllowOverride FileInfo AuthConfig Limit
    Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
    <Limit GET POST OPTIONS PROPFIND>
        Order allow,deny
        Allow from all
    </Limit>
    <Limit PUT DELETE PATCH PROPPATCH MKCOL COPY MOVE LOCK UNLOCK>
        Order deny,allow
        Deny from all
    </Limit>
</Directory>

What am I doing wrong? I was playing with clamav, clamav-freshclam,
clamav-data and clamav-doc packages. Also with snort, snort-mysql and
acidlab.

I cannot figure out if one of the above packages has ruined my Apache
install.. At least I dunno how to ;) I am positive it did work this
morning, and that I didn't alter any file-system permissions. I checked
to be 100% sure, and these public_html dirs are all perfectly accessible
(x and r rights to all)

Can anyone give me some advice on how to continue please? I am searching
for an hour now and I am totally puzzled to be honest :(

Best regards,
