 * Hi everyone! I have error 404.
 * I migrated my site and now, the polylang doesn’t work like before! But, if I 
   deactivate the permalink, it’s works, but internal pages can not be displayed
   in either English or Spanish. Even I need the SEO like: …/en/home or …/es/inicio,
   and all my internal links.
 * I saw that my new site has version 2.2 polylang and the old site has version 
   2.1.5, do you know if is this the problem?
    Help!!! Please!! This is my site 
   that doesn’t works: [http://rev.mex.biodivers.unam.mx/](http://rev.mex.biodivers.unam.mx/)
