I developed a project and sometime later client faced that they are not able to saved data, so I checked database table, the table have more than 10 columns text type.
I googling and find out that table engine is InnoDB and InnoDB limitation row length of 8000 bytes, thats the problem,
I changed it to MyISAM and test, it working properly
ALTER TABLE `table_name` ENGINE = MYISAM
Its work with me now.
