MySQLi插件未加载

Question

I recently upgraded to MySQL 5.7.9 from having previously used 5.5 (by removing the old mysql and installing the new one). Now when I run a PHP script (which used to work), I get this error:

Warning: mysqli::mysqli(): (HY000/1524): Plugin '*8CC466EE1F3C4B48CF50D1E337EE808AC922A16E' is not loaded in...

Any idea how to fix this?

Answer 1

As it turned out, in my case, the user record in the mysql.users table didn't have the full grant privileges and was causing this error.
