Thank you very Much Erik as well as everybody that answered on the

getting other problems.

Just to be more precise, all the articles on our

"erased" so we end up with hundreds of blank pages, the first time
it happened I had started to manually go back from the history
and restore all the pages but the content keeps being erased and
this is being done over a very short time, I guess there's an
automatic process doing this.
As has been pointed out, you're running a MediaWiki version that
has a bug which can lead to database corruption. Upgrade to version
1.3.17, 1.4.11 or 1.5.0 ASAP to avoid serious and permanent loss of
data. The 1.5.0 upgrade process is the most dangerous of all these,
so make sure you have backups.
Until you do so, I suggest locking the database - if you have the
necessary permissions, you should be able to do this using the page
Special:Lockdb. You can also manually lock it by creating the file
specified in $wgReadOnlyFile in your DefaultSettings.php.
1.5 has many security measures (rate limiting, SORBS proxy
blacklist, support for spam blacklist extension etc.). Until you
figure out which method is the most effective, you may want to
simply disable editing by anonymous users. In 1.5, this is done with
$wgGroupPermissions['*']['edit']=false;
in LocalSettings.php. This will not help against a determined
attacker, but may be enough to deter drive by vandalbots or
spambots for some time.
HTH,
Erik
