We have released an update to validate.php which will tell you if your dbSchema is wrong - we expect most people will be hit by this. Validate will provide you the queries to run to fix the issue but we’d like people to report those recommendations here first / as well so we can be sure the code is 100%.
Just as an FYI, your posts will be deleted once we’ve used the information and you’ve confirmed everything is ok - please don’t repost unless you have further issues.
