This error message typically occurs when the MySQL server is unable to locate the errmsg.sys file. This file contains error messages that are used by the server to communicate with users and applications.
To resolve this issue, you can try the following:
Check if the errmsg.sys file exists in the MySQL installation directory. If it does not exist, you may need to reinstall MySQL.
Check the MySQL configuration file (my.cnf) and ensure that the path to the errmsg.sys file is correctly specified.
Verify that the MySQL user has read access to the errmsg.sys file.
Restart the MySQL server and check if the error message persists.
If none of the above solutions work, you may need to seek further assistance from a MySQL expert or support forum.
