"error 1064 when I change module title Chek out my hot works

Hi,
I changed the Chek Out My Hot Works module title and the website is off
I have to unpublish the module to recover the website.
I kept the way title was written with hooks [br] and [icon_flame], just changing the words and the frontend crashed
I tried then to write only one word "decouvrez" and it stood with 1064 error
the only way is to unpublish the module.
Any idea on what is the problem ? Did anyone have the same issue ?
(Website is at local install at this moment)

OK
the publish date was empty after I saved the module (Why ???)
I added today date and the website is on again
but the module is no more displayed on FO, I don't know why.

I solved the problem installing a new fresh John local website
I copied the module SQL table and pasted it in the 1rst John local website DataBase replacing the table that displayed the 1064 error
and it works now. Maybe there's a gremlin in my computer...
