"Moved" installation: form not found

Hi,

I’ve moved my installation from a subdirectory to root (test.mydomain.com -> https://www.mydomain.com) using “Giving WordPress Its Own Directory”.

But now, after I’ve installed the plugin, the button appears though, but when I click it, the 404 page shows up. I’d guess I’ll have to adjust some path, but I don’t know where.

Best regards,

Andreas
