Thanks, It worked! But now I have a different problem. Suddenly, I'm getting the following error when I try to connect to my database from PHP: > Connect Error: SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client PHP might show this error > Warning: mysqli_connect(): The server requested authentication method unknown to the client [caching_sha2_password] in D:\xampp\htdocs\reg\server.php on line 10 How can I fix this problem?
