Error while sync database

Hi there,
I’m new to PHPRad, now using PHPRad Classic v 2.7.3.
I worked a while with normal and smooth, for some reason I need to change MySQL database charset to utf8mb4 and collation utf8mb4_general_ci with direct script to database:
ALTER SCHEMA MyDB DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_general_ci;
Now I encountered error if I sync database from PHPRad as follow:

And still having error after I rollback my charset to latin1_swedish_ci.
Is there any advice ? Thank you for your concern.

This might help you with a solution:

You can set the charset your database is using here. This might be the solution.

Hi Willvin, Thanks for your reply. I will try your solution.
I already register those forum for PHPRad classic v2.7.3, but unfortunately activation email seems not reach my email so I cannot continue to login.
