CheckView does not currently support WordPress Multisite installations. This applies to any setup where multiple subsites share a single WordPress core, including:
Our testing engine, plugin authentication, and data-mapping processes are designed around single-site WordPress environments, where each site maintains its own isolated:
Because multisite networks share resources and handle plugins, users, and URLs differently, certain test-generation and validation steps cannot reliably operate in a multisite environment at this time.
With that said, individual test flows will generally run on a WordPress Multisite installation, but WordPress-specific functionality such as CAPTCHA bypassing, database submission verification, and email submission verification is not supported in a multisite environment. If those options are disabled, most test flows should still operate as expected and you can continue to use alternative validation steps such as asserting that a confirmation message appears.
