I have same kind of problems. When I update it won’t run upgrade.php. Claims that server cuts connection. When I go to main site it has this message on top and on every post too:
WordPress database error: [Table ‘sfi9xxxx.wp_terms’ doesn’t exist]
SELECT t.*, tt.* FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON tt.term_id = t.term_id INNER JOIN wp_term_relationships AS tr ON tr.term_taxonomy_id = tt.term_taxonomy_id WHERE tt.taxonomy IN (‘post_tag’) AND tr.object_id IN (219) ORDER BY t.name ASC
Don’t really know what can I do. I checked the link provided on this thread and then checked the db version number but it is 4773 like it should be.
I’m upgrading from 2.1.3
Luckily I have backups. so back to version 2.1.3
