New task don't get written to database

I have followed the how to start guide. I can read data from the database and I can update it(only if I created the task in database myself). Only problem is when I create a new task it doesn’t get added to the database. I’ve been trying to figure this out for days now any ideas ? I’m suspecting it’s something to do with date.

Using MySQL 5.7.14, Apache 2.4.23, PHP 5.6.25

please try enabling logging as shown here: … idelogging
Then you’ll be able to see the error message in generated file.
As for the possible cause of the error - please check your table schema and make sure ‘id’ have auto increment value.

I can confirm this happening when using a db other than MySQL. I am using Oracle.

I changed the column type of start_date to varchar and task creations now insert into the tasks table.
