WP Super Cache & GTranslate Pro

I’m using both of these plugins.

For a long time, there were no problems. But now, Gtranslate has stopped working. I’m getting 404’s if I try to translate.

Are there any settings I should be aware of in Super Cache when using Gtranslate (redirect method)?

Thanks.
