I also get the same error when I try to activate this plugin (Getting error: unexpected T_String on line 777). I am with WordPress 3.9

Thank you, Ipstemu! I will test it ?? Hope it works well with the qtranslate plugin, which we used to translate the web site.

I agree with what you say but also f.e.:
If you want to use Google Webmaster tools and there to set different Geotargeting for the two language versions:
domain.com/bg
domain.com/en

Than you have to add them in Google Webmaster Tools as two different sites, so that you can give them a Geotargeting for specific country. Which Google says “This will also improve Google’s search results for geographic queries.”

So 2 different sitemaps will be needed to add it both sites, because you can not send Google the same sitemap with all links in both sites.

Yes, becauause it is better according to many seo specialists to have different sitemaps for every language:
