Nextgen conflict

An several websites I use the Roots theme (6.4.0 or lower) that will give a conflict after updating NGG to version The router->get_static_url creates a path which misses the first forward slash. for example some url should be:… but ngg creates: site.comwp-content…

When I install the latest version of Roots if workts fine. Any Ideas how to solve this?

Try removing the root relative URL / clean URL rewrites functionality in that version of the theme?
