If you’ve had problems with WordPress permalinks in Greek or any other non-Latin language, where text appears as “?????”, here’s the solution! Thank you “Doktoras”, you’re ELVIS!!!
It’s in Greek, however, so here’s a rough translation (replace “greek_general_ci” with your language):
First step: In cPanel, go to MySQL® Databases and then to phpMyAdmin, where you pick the Database your WordPress is using, and then Operations. Under Collation, pick greek_general_ci and Go. Close MySQL® Databases
Second step: Open wp-config.php and in the line “define(’DB_CHARSET’, ‘utf-8‘);” change utf-8 to greek_general_ci, then Save and you’re done.
Brilliant. Thanks again “Doktroras”!!
