Subversion E160013: '/svn/xxx/!svn/me' path not found* error

I resolved this by disabling the HttpV2 protocol. To disable it you can make changes to the mod_dav_svn configuration locations as follows:

DAV svn...SVNAdvertiseV2Protocol Off

Just wanted to add a little to this "question". I was getting the same error message after I relocated a SVN server from one machine to another. A 500 error and "!svn/me" was appended to the end of the SVN server URL, nothing would commit but everything else worked. After hours trying numerous things, it turns out that the user account VisualSVN / Apache was using didn't have write access to the SVN repo's directory. So I gave the account modify / write access ot he SVN repos directory and committing worked. Which actually makes sense because everything but Commit was working. Not sure if this will be helpful for others but I thought I would post it here regardless. Thanks for the question, helped me understand where I went wrong.

This was a problem on https://trac-hacks.org, which serves Trac at / and Subversion at /svn. The issue was initially worked around by disabling SVNAdvertiseV2Protocol. Later the issue was resolved by serving Trac from /trac and redirecting / to /trac. However, that solution was not ideal due to the redirect. Another admin on the project found the solution of adding:

Alias   /svn            /var/www/000-default/svn

I'm not sure why this works, but it effective and doesn't require the redirect and serving Trac from /trac.
