What is the cause of these errors and how can I fix it?

Answer 1

This is how it was fixed for me :
Open shell and start MySQL with this command:
mysqld –-console –-skip-grant-tables –-skip-external-locking
Repair database with this command:
mysqlcheck -r --databases mysql --use-frm
Stop MySQL, restart MySQL from XAMP.
