Problem: The client purchased a 1yr subscription to "WPML Multilingual CMS" and is considering upgrading to "WPML Multilingual Agency" due to hosting 26 client sites on a WordPress multisite network, each with multiple environments, totaling 78 sites. Solution: We informed the client that when using Multisite, it is only necessary to register the main site using the site key. There is no need to register the subsites, as this is not supported.
If this solution does not fully address your concerns, or if it seems outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If further assistance is needed, please open a new support ticket at WPML support forum.
