First and foremost, great job with your plugin. It is working very well and this even though I am using an Avada theme, optimized for WPML.
I have one pb though. I am using 2 gravity forms to collect festival submissions. One is in French, the other one in English. The English one works fine (English being website primary language), but the French one breaks as soon as I try to reach the 2nd page of the form.
French form: http://muvi.ca/fr/soumettre
English form: http://muvi.ca/en/submit
The post request when switching to next page returns a 404...
Anyone can help?
