a wrong chmod command rendered all my repositories unaccessible

Dear SVN experts,
I'm administrating a SVN server for my lab with several
repositories/projects accessed via SSL+DAV. The server runs on an old
mandriva (2009) with subversion 1.5.2 and apache 2.2.9 with mod_dav,
mod_ssl and mod_dav_svn installed. Repositories are separate directory
associate to the project.

A couple of days ago doing some cleaning on my server I've executed a
«chmod 700 -R *» on the wrong directory (to be precise on /home/svn) with
the result to render inaccessible the access to my repository from
remote, as in the following case:
>svn checkout https://url/svn/thales/trunk
   svn: access to 'https://url/svn/thales/trunk' forbidden

I can't do update or commit as well. Before that catastrophic error
everything was working well. I can't access neither from the command line
nor from firefox.

I've tried to change back the correct access rights but with no luck and
also a «chmod 777 -R *» on the same directory didn't help. Also
restarting apache doesn't help.

What am I doing wrong? Attached to this message you find the current
situation of one of my repositories with what I consider correct access
rights.

I hope you can help with my problem.

Thanks in advance for all the help
Walter
