Unless I missed something big time, I don't see a way to display event descriptions etc on multi language J1.7 sites.
The keywords and component texts are all translated but now my only work around to show my clients multi language events descriptions is by making all categories double and also double the events in them in two languages.
It works but does not work when setting max seats or using waitinglists....
Please have a look at this.
