Documentation not accessible for older version (5.X and 6.X)

There are some corrupted links in the home page of the documentation:

  • Starting from your web site http://documentation.bonitasoft.com

  • Click to an older version (for example 6.5) in the top of the page

  • And then click to any direct link from the right side of the page

=> It always load the documentation for the version 7.0 or 7.1

But unfolding the table of content at the left to access the wanted section links to the good pages.
