Chouby,
It works ! Awesome, thank you ! I have two last small questions and some additionnal feedback informations:
1. Questions:
1.1 Is it normal and ok that the "Events informations" custom fields appears also a second time in the list of user-added custom fields just below ? It happens for all languages, even the first one.
1.2 Do I have to delete the development version you gave me and wait for you to implement it in a official release or can I keep it as a normal version ? I am afraid it is going to interfere somehow with the update mecanism or something else.
3. feedback informations: I tested some possibilities when custom fields are modified to see if the modification would be synchronised. I tried to modify a field in the english version but it didn't take in the german and french version, the data was still the old one. But I don't need to have that advanced functionnalities. I mean, your plugin is free, so great already, even better with the modification you added in your last post. I sent you that information just in case you would need it in the future.
By the way, I cannot believe I could be of any help right now with my ultra-low level in PHP programming. But do you need some help with basic stuffs (translation english-french or things like that) ? If so, tell me. I don't have much time but I'd be glad to do what I can.
Thanks a lot !
