Can’t access staging dashboard

Hi,

I recently downloaded and activated the WP Staging plugin on our website. Unfortunately I canno’t access the staging dashboard environment. When I open the staging site I get a login form and after entering my credentials I get the see our site with the top bar where is stated: “Staging – our website name Dashboard”. (the top bar is not orange but dark grey).

When I click on Dashboard I get a page not found error. I am unable to access the dashboard of the staging site. I also tried to add wp-admin (and our custom slug) to the url, but no success.

I also installed the plugin to another site of us, which is hosted somewhere else. There I have the same issue.

What am I doing wrong?

Kind regards,

Bianca
