We show a variety of warning messages in the server HEALTH column as needed. Most are simple warnings but some of them are important and need to be handled quickly.
Keep in mind that the messages in the health column only update ONCE every evening. Thus, even when you resolve an issue, you might not see messages updated or removed from the column right away. You can force an update sooner by scheduling callbacks to run using the options under the CALLBACKS tab for the server.
The default PHP server version is what’s used to run wp-cli. WP-CLI is an integral part of your WordPress server infrastructure. If it fails to run properly you will not be able to perform common actions such as changing your domain and cloning sites.
The correct PHP version to use is a little tricky. This is because not all plugins and themes are yet fully compatible with PHP 8.x. Even the ones that state they are compatible still throw deprecation warnings into the WP error logs.
If you know that all your plugins and themes do not throw errors with PHP 8.x, you can set the default server PHP version to 8.0 or 8.1.
However, for maximum compatibility you can use 7.4. Note that 7.4 is no longer receiving security updates; so if you can, it’s best to use 8.0 or 8.1.
You can change the default PHP version for a server using the TOOLS tab for the server.
This message shows up when we’re unable to get a count of the number of updates needed for a server.
To resolve it, you usually have to run ALL server updates from the command line. When the updates are complete, you then need to restart the server.
While you can attempt to run the updates from the WPCD Server UPDATES tab, there is no guarantee that they will work – the best way to run them to resolve this message is to do so from the command line.
This is a count of the number of non-security related updates available. These are usually optional updates and are best run from the command line. While you can attempt to run these updates from the WPCD Server UPDATES tab, some of them might require user input so it’s best to run them from the command line whenever possible.
