Incompatibility with Polylang

Though I doubt this will get updated (I’ve hacked the code so that it works for me) but just FYI.

There’s an incompatibility between this plugin and polylang plugin if you’re using language sub paths (eg. example.com/en/, example.com/de/, example.com/fr/) and you have any url path which have subdirectories (eg. example.com/file/xxx, example.com/blog/xyz) then custom permalinks manager tries to look at polylang settings determines that we /file/ or /blog/ isn’t valid language codes and then strips them from the $request parameter and then checks if the $request parameter matches the set permalink, (which it wouldn’t do because it modified the request) and determines that it needs to redirect to the permalink url and then it enters a permanent redirect loop.
