I installed LyftenBloggie and I already have joomsef which was working perfect until now, after I installed that blog program, I start having problem, 1st problem problem when I switch language, sometimes only arabic works, and sometimes only french, I cannot switch, in the url I see the fr or ar but it show only one language.
second problem and it is what it really bother that the add of new entry does not work, when I check the url on artio URL and I test the real url it works, but the sef url does not work, and the worse when I choose add new entry on the homepage of my website a very different url appear and it does not exist ont he list of the JoomSEF URL Manager 's list.

please advice
thank you in advance.

here is the links

the real url
index.php?option=com_lyftenbloggie&view=author&layout=form

the Url appears when I click add new entry
ommafilmassih.com/blog/--/author/new-entry?lang=ar

should be
ommafilmassih.com/ar/ajouter-un-blog
and it exist on the list of url and the real url front of it is the right one
