Or you can disable it fully as this just only activated strict mode again when you restart your vps.
To disable it fully, here's the steps:
Step 1: Go to C:/Program Files/MySQL/my.ini
Step 2: Locate "sql-mode"
Step 3: It looks like: sql-mode="NO_AUTO_***********"
Step 4: Remove everything in the speech marks so it then looks like this: sql-mode=""
Step 5: Save the Document then close it
Step 6: Right click the start menu and click "Command Prompt (Admin)
Step 7: Type: net stop MySQL
Step 8: Type: net start MySQL
And now sql will never be in strict mode!
Or you can take a look at the screenshot and see it's trying to update the exit_timestamp with the value 1499739649,7621 - it's using a comma not a decimal, their set decimal is wrong.
