If an error message appears after clicking "Connect my site", here are the most common cases:
To disconnect a site, you can do it from your wp2ai account or from the WordPress plugin settings: the two sync automatically, disconnecting from one side disconnects the other too. This disconnection takes effect immediately, with no delay or caching.
If you manage multiple sites (Agency account), each site has its own independent connection: disconnecting one site does not affect the others.
If a different error message appears, contact support with the exact text shown.
