SVN takes control of port 80 after setup

[Salam Y. Elias]

Hi, Since I have setup SVN, it took full control of port 80 on the
apache server. I browse correctly to http://mylinux/repo but not any
other applications, for example http://mylinux/bugzilla or
mylinux/phpmyadmin.....I get an erro when browsing any other
applications as follows

<D:error><C:error/><m:human-readable errcode="2">
Could not find the requested SVN filesystem
</m:human-readable></D:error>

Thanks for your help
