Hi
It was the mysql config that was causing this issue.
I had troubles installing zencart , I had to apply this fix:
https://www.zen-cart.com/showthread....57#post1268657

It seems that with sql_mode=STRICT_TRANS_TABLES, you can't insert authors and authors types ( didn't test the others fields)
So today I changed to
sql_mode=NO_ENGINE_SUBSTITUTION

Usually I'm on Nginx with the same db, but never saw this error in other scritps. But for zencart I've used xampp, that had it's own db. I've change to a lamp cause I'm on linux, and this errors stared to come up.
everything it's ok :)

Thanks
