Hi,
Thanks for reporting this. The instruction contains a naming error: please look for Tools → PHP
Compatibility Scanner, not “PHP Compatibility Checker.”
You must be logged in as an Administrator. If this is a multisite installation, please check Tools in
an individual site’s dashboard rather than under Network Admin.
You can also try opening this URL directly:
https://your-site.example/wp-admin/tools.php?page=php-compat-delta
If it still doesn’t appear, could you send:
- A screenshot of the plugin shown as active on the Plugins page.
- A screenshot of the expanded Tools menu.
- The plugin version, WordPress version, and PHP version.
- Whether this is a multisite/network installation.
- Whether an admin-menu customization or security or permissions manager plugin is installed.
Sorry for the delay in a response. I was away for a few days for personal matters.
