Hey Erick,
Thanks for reaching out to us!
Unfortunately, although our plugins are translation ready, the Community Events plugin isn’t currently guaranteed to work with mulit-language plugins such as WPML or Polylang. On this note as well, we’ve elected to support WPML for this functionality and currently support it for our core plugin and Events Calendar PRO. We are working of more complete compatibility across our plugin suite.
Currently, the front-end form will only be translated into the main language set for the WordPress installation.
I apologize for any inconvenience here.
Thanks!
