Some kind of bug with sobipro ?

Hi ! thanks for developping this new version of jat3... megamenu are better, weight is enhanced///
So my problem is this one :
1/ i use the last version of jat3 and the blank template on this site : http://iwantout.eu (i tried to reproduce as well as i can something close from teline IV template )
2/ i also use sobipro for creating a directory (latest version)...

I can create an entry with sobipro :

1/ I can see the "vcard" here : http://iwantout.eu/art-culture/musees/ (it's the short description)
2/ i have a white page when i access the detailed page : http://iwantout.eu/art-culture/musees/313-fondation-vasarely


Is there someone who could tell where this issue is coming from ? When i use other templates it works correctly.
Best regards
