Problem:

PHP warnings when using PHP 8.2

Solution:

Toolset is not fully compatible with PHP 8.1+ yet.

Please consider that the items that you gave the screenshot are not breaking errors. Those are deprecation notices.

That means it works now but it will not in the future PHP versions such as PHP 8.2+.

So for now you can just hide the notices as everything seems to be working ok.

Add the command below to wp-config.php file of your WordPress installation:

Problem:

I have got this error:

Fatal error: Uncaught InvalidArgumentException: Upgrade command not found. in
/wp-content/plugins/types/vendor/toolset/toolset-common/inc/autoloaded/upgrade/CommandFactory.php:23

Solution:

- IMPORTANT STEP! Create a backup of your website.
- Delete Toolset plugin files
- Use the installer to install all Toolset plugins.
