WP 5 upgrade and ALTER TABLE wp_post … post_password

Maybe I’m blind or I’m overlooking something, but… I don’t see any tickets related to that subject in any of these releases: https://core.trac.wordpress.org/query?status=closed&milestone=5.0&group=component&order=priority https://core.trac.wordpress.org/query?status=closed&milestone=5.0.2&group=component I also don’t see any DB operations in code: https://core.trac.wordpress.org/browser/tags/5.0.2/src/wp-admin/includes/upgrade.php#L1820 https://core.trac.wordpress.org/browser/tags/5.0.2/src/wp-admin/includes/upgrade.php#L1946 So I don’t think that these ALTERS come with WP. Maybe some plugin (or theme) is responsible for this. If … Read more

Does WordPress run install/uninstall functions on plugin upgrade?

No, the activation, deactivation and uninstall hooks will not be run when the plugin is updated. So when your plugin is updated the page will still be there (assuming the user has not deleted it), and it will not be deleted on uninstall if your plugin no longer does this on uninstall. If you want … Read more

Subscribers become Authors after Upgrade? / Mass Update of Users?

Hi @Bee: I have no idea why this happened. But if I understand your problem correctly you need to set these user records back to being ‘subscriber’ instead of ‘author’, right? Normally I would not recommend direct SQL update like this but given the nature of the problem and it being a one-time thing I … Read more

Upgrade Nightmare – No Posts, Permissions Issues and Can’t Create a new post

I had some problems upgrading to 3.0.3 on a multi-site installation. I had used the automatic upgrade and it failed, but luckily, downloading and extracting the new files from WP.org and uploading them directly fixed it. I would try that first. If that doesn’t work, try re-uploading your backup files. You did make a backup, … Read more

How can I transition a site from using the Beta Tester plugin to a “normal” install?

How a deprecated function can crash WordPress site while upgrading

Where… The following files hold the deprecated functions: ~/wp-includes/deprectated.php ~/wp-includes/pluggable-deprectated.php … Take a look at them and then through their replacement functions, where the calls to _deprecated_function() happen. Why… Normally a crash shouldn’t happen. In the “real” PHP world, you’d get an E_DEPRECATED Warning. In WordPress you’ll get a trigger_error() return caused by _deprecated_function() calls. … Read more

Why is it bad to use the GUID?

In a nutshell – GUID is not supposed to hold meaningful data and the fact that at this moment the data in it happens to be meaningful is coincidental. WordPress does no verification whatsoever that GUIDs mean anything. They are not guaranteed to stay immutable if you rely on that and they are not changed … Read more

Can I degrade back to 3.7.1 from 3.8 by just coping old wp files?

Short answer – who knows. Will probably work, maybe something will explode. Behavior is undefined for backwards direction. Long answer – from quick look at code 3.8 upgrade doesn’t seem to do anything specific to database, so likely it will be pretty painless. For any serious site – make a staging copy and test it … Read more
