I tested your extension on a J 3.2.2 site. The demand to disable the language filter plugin makes it impossible to work with this multilingual site because of missing language associations.

Nothing to find where I can manage the associations between categories, menu items or articles for my languages.
Nice that JoomSEF works but I cannot work with the CMS itself.

Sorry what is the sense of your extension when you kick out a main feature of J 3.2.2? Or do you really expect that for JoomSEF each language gets it's own Joomla installation?

Hello,

We know about the limitation of current version of JoomSEF that it doesn't support multilanguage associations due to changes in Joomla's code. We'll fix it as soon as possible.
I'm sorry for the inconvenience.
