However, this one is not a buggy one like the others. I have tried SEF404 and AceSef and both of those are either way too complicated to manage, or do not adhere to rules properly. Yet here with this one by Artio, things are working properly and there is no more confusion about what is going on. Locked urls stay locked unlike others that do not. Also we use JotCache and it works in sync. I am using a free version which is not great because they have to put their links all over the place, they should give us a choice about where these are going to be put. I see that others rate it low, but believe me, they will also rate the others low because of the learning curve. This one looks a lot like a knockoff that came lately, but it manages links much more smoothly and consistently.
If you had asked me, I would have said to you that you probably download a plugin addons (breadcrumbs or xmap) instead of the module itself !
It works without specific configuration like the native menu in joomla. For the langage, you should have seen that all the pages for maximenu_CK are translated in english, and the admin params too.
