One or more database tables are unavailable.

Hi,

I was getting the error message ‘One or more database tables are unavailable’ so I repaired the database, and now it says that ‘some database problems could not be repaired’ and to paste them here:

wp_users: 3 clients are using or haven’t closed the table properly
wp_usermeta: 4 clients are using or haven’t closed the table properly
wp_posts: 8 clients are using or haven’t closed the table properly
wp_comments: 10 clients are using or haven’t closed the table properly
wp_options: Table is marked as crashed
wp_postmeta: 13 clients are using or haven’t closed the table properly
wp_terms: 1 client is using or hasn’t closed the table properly
wp_term_taxonomy: 2 clients are using or haven’t closed the table properly
wp_term_relationships: 3 clients are using or haven’t closed the table properly
wp_commentmeta: 10 clients are using or haven’t closed the table properly

Any ideas on how to fix this?
