Vbet 2.4.4, "language=" parameter not generated in in CMS

[vforum]

Vbet 2.4.4, "language=" parameter or (i.e. '/en/address') URL not generated in CMS


so all the links within CMS return to default english language


however it can browse rest of the site fine in different languages, forum,blog,etc

same error in both of these options:

Add language parameter to URL (i.e. 'address?language=en')
Create URL's according to SEO link consensus (i.e. '/en/address')
