I get this error;
Error detected: This site already contains a link. Please deactivate and reactivate the MainWP plugin.
Hint: Go to the child site, deactivate and reactivate the MainWP Child plugin and try again.
I have the main domain connected localview.us
but for some reason this new subdomain install is not working.
I even tried a unique security code under the mainwp settings.
This usually means there is already a connection to the MainWP Dashboard Installation. Is the RED WARNING window visible on the Child Site admin? If it isn’t then there is a link setup already & you will need to disable & re-enable the MainWP Child Plugin on the site you wish to connect to.
