Cannot see all plugins page


I am doing a migration to Multisite and want to use your plugin Domain Mapping. However I am not able to add it to my website. When I open this page:
with Admin user I am told that I am not authorized to access this website.

When I try to manually install the Domain Mapping plugin on my test website I am sent to:
which again shows the same error.

What can be the reason for this error? How can I install the plugin by uploading it's code - I need to add the plugin's code to our repository in any case.

    Hello Anton Ruzhekov,

    I hope you are well today.

    WordPress Multisite has a different Dashboard for managing plugins and themes network wide than standard standalone WordPress.

    When you login to the Network admin, the Dashboard URL should be like:

    The URL to the WPMU DEV Dashboard, where you would install Domain Mapping, should look like this:

    If you're getting a permissions denied error at the above URL, it could be an issue with how WPMU DEV Dashboard was setup. Did you setup the plugin with the same user account you are logged in with to try to install Domain Mapping? By default, WPMU DEV Dashboard is only accessible to the Super Admin that installed it. This can be changed in the settings; however, by going to Network Admin -> WPMU DEV Dashboard -> Settings -> Permissions.

    If you are certain you've DEV Dashboard using the same account that you're installing Domain Mapping with, then there may be another issue. If that is the case, would you please grant me access to your site and server so I can look into this issue further for you?
