MU enabled site.
I used to have another plugin doing the stop word removal (SEO slug) but found that it stopped working and since it's not in development longer I disabled it.
I was looking for a new plugin when I found that my SEO plugin should be able to do the job, but something seems to be wrong.
I've seen previous posts on the same issue but there the answer was a bug in an earlier version of the plugin.
Any ideas on why it's not working as it should, and what can I do to debug it ?
