I get these errors:
Warning: proc_open() has been disabled for security reasons in /users/mythos94/www/traq/include/svn.class.php on line 99
Warning: proc_open() has been disabled for security reasons in /users/mythos94/www/traq/include/svn.class.php on line 59
Warning: Invalid argument supplied for foreach() in /users/mythos94/www/traq/templates/default/browsesvn.php on line 25
My SVN repository is @ code.google.com (Googlecode) and it isn't shown ... but it's the right adress.
Looks like your host has disabled the proc_open function, It's not Traq.
