farsi links don't work

[kooshiar]

The problem is with the url
if you replace /fa/en with /en it goes to the english version
couldn't find the right url for the farsi lectures

[kooshiar]

now if you replace /fa/en with /fa you go to farsi pages
if you fix the links in the homepage everything is good to go

This seems to have been already fixed.
