Problem with Thai language

Dear phraisohn,

We have checked and realised that your wp-config.php might have the collate as utf8mb4_unicode_ci which should actually be utf8_general_ci
In later versions of WordPress it started using collate and characterset as utf8mb4 but in order to have language other than English we must have collate and characterset as utf8.

Here’s how it should look after you change it in wp-config.php

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');
/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', 'utf8_general_ci');

I am marking this as resolved, please do let me know if you still face any trouble.

Note: the entries which are already made [i.e. which shows question marks right now] would not get automatically converted, but the entries made after this change would work absolutely fine. Previous entries would not change because they are already posted as question marks and there is no rolling them back.

We are updating some of the code in our plugin to have a permanent fix for all the users.

But in the mean time, also try one more thing, if you can…

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', '');
/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');

i.e. leave both of it blank, it should work.

If it doesn’t; do not worry at all, we will get you the solution. I promise.
