Firstable, I´m designer, hence my ignorance. It´s been awhile since I didn´t updated a site. The client asked me to make a new member in EE. I´ve been able always to do that on the spot, but this time I always get the SQL error of the email subject (1364). After some researching, I tried to publish some entry and I got the same SQL error.
Then i found this post here Database Error 1364 in Solspace Calendar
The point is that i´m not sure if I have to adding a default value (0) to all the tables or there is a way to do that for the whole site.
Thank you in advance
