Before I installed SEO Strict URLs I had a container ’www.example.com/news’ and a resource ’www.example.com/newsletter’. After installing the plugin the container changed to ’www.example.com/news/’ as expected, but the resource changed to ’www.example.com/news/letter’. For the time being I simply renamed the resource to mailinglist. Is this a bug in SEO Strict URLs or simply a side effect you just have to put up with?
