vladaman on "[Plugin: Polylang] Redirect removes Query String"

Hi,

when using Polylang all incoming visitors are redirected with 301 Permanent Redirect to their appropriate language pages.

Unfortunately during this redirect all Query String parameters and referrers are lost. This affects Google Analytics tracking for example so we don't know where is traffic coming from. Is there any solution?

Example:
curl -I "http://www.dotykacka.cz/cs/home/?utm_source=sigroup&utm_medium=website&utm_campaign=backlinks"

HTTP/1.1 301 Moved Permanently
