I don’t think anything has changed in the plugin’s code for linking topics recently. Have there been any recent changes to your WordPress site? For example, have you moved it to new hosting, or changed the version of PHP that it’s using?

The domain name is parsed from the URL with `wp_parse_url`. It is possible that it’s not parsing the domain correctly.
