I recently migrated from qTranslate to mqTranslate, and now I'm seeing double language tags on the URL when I use
bloginfo('url'); and pre-path mode.
Somebody was having a similar problem here, a couple of months ago:
I have the latest version of the plugin, but the issue persists.
Please let me know if this will be fixed in the near future, or if there's anything I can do on my end to fix it.
Thanks a lot!
