I have Debian 8 (Jessie) server and i followed this procedure to upgrade from mysql 5.5 to mysql 5.7 https://dev.mysql.com/doc/refman/5.7/en/linux-installation-debian.html
Now, any script in the server that have an INSERT query is not working... The script is being executed but the INSERT query is returning always false with no error description...
Any ideas how to solve?
