I was able to fix wp_commentmeta. I did this by;
1.) going into the server files, to the database files: / var/ lib/ mysql/ ddm_wp_ddmsrealm/
2.) I removed wp_commentmeta.idb
3.) I imported wp_commentmeta from a backup
4.) Table now appears and can be accessed.
However, if I try this same method on the other two tables it fails. I delete the idb files. Double check they are gone. Then try to import from phpMyAdmin. I get this message: #1050 - Table 'ddm_wp_ddmsrealm.wp_forum_posts' already exists
Then when I go back into the server files the .idb files have returned.
So odd, does anyone have any thoughts on this?
