Three months after finally works, I get a 500 error but it works. I see where the error is: create a new network of testing before accuse the plugin does not work well.

Currently says Error 500 but it works and my users love this. 

Is there any chance of translating it into other languages?

You can translate this plugin to any language you like if you have some coding knowhow.

I will see if i can repeat the 500 error on my testsite and get back to you.
