Fix WP-Admin posts dated to 1969/12/31

You’ll need to either edit them manually, or run an SQL command in your database to change the date of each post.

Are any of these published posts or are they currently set to be drafts?

What do you have set as your timezone in settings -> general?

Thanks for the quick reply.

These posts are directly published. And I set my timezone to Hawaii UTC/ -10

This date will be shown when the value for a date is null. I have heard of cases where unpublished posts viewed in admin have shown this date.

Can you post the URL of your site please?

Has problem just started occurring – ie were the correct dates displayed previously? Do the dates display the same way on the site front-end? If you press the publish / update button for one of the posts, does the date change?

Here’s the url: https://www.pacificcardiologyhawaii.com

The dates are displayed correctly on the front-end.

When I tried to update them via wp-admin the dates are still the same.

I really appreciate your help. Thanks a lot.

If the dates are displayed correctly on the front end, they cannot be null in the database.

Can you deactivate all of the plugins and check to see whether the problem is still present. If the dates then appear correctly, activate the plugins one-by-one and check each time until the dates show incorrectly again to find out which plugin causes the issue.

If deactivating all plugins makes no difference, check whether the dates still display incorrectly with the theme switched to twentytwelve.
