Hi @jamesosborne

Thanks for your answer.

Point 1: no, that was a new installation
Point 2: the URL is https://cmatrix.ch/wp-admin/?action=googlesitekit_proxy_exchange_site_code&googlesitekit_code=sitekit-QEFLC9dsAH3oprEfHV38ED&googlesitekit_site_code=4%2F0AfgeXvt6Q1bz9XEZzBAB-qTkPQwHkWK0xRSn5F-kQckXbNGxUpNNnHeOXQXyh2AUuRATyA&nonce=bf9de043ea&step=verification

Oh, my wp installation is under wp/wp-admin not only wp-admin.

I changed the link to ../wp/wp-admin/?action…

and it worked!

thanks a lot.
