@sushant.naik We went over this before in Question Saving Failed
utf8 is not the same as utf8mb4 - and latin1 is going to get you into a lot of problems unless you’re only storing old European texts.
And you’re not posting if you have actually converted the database+tables+columns.
Let me make it very clear: If you use MySQL/MariaDB, then you are required to use utf8mb4.
If you don’t know how to set that correctly, then I would suggest that you migrate to Postgres instead.
