I got a problem with qTranslate not appending the language HTTP GET parameter to any of the menu links.
See here: http://bit.ly/12nNfDu
Then I further investigated the issue. It really seems only to affect SSL-protected sites.
I just updated to WP 3.5.1 and qTranslate 2.5.34
Is this a known issue? Can it possibly be traced back to WP SSL?
If yes, can you make the two very popular plugins play nice together?
