I'm trying to install the WPMUDev Dashboard plugin on a new website (like i did successfully dozens of time in the past), but I don't know why, on this specific website it's not working.
I uploaded the plugin files in wp-content/plugins as always... Then in the "Plugins" menu, I click "Activate", which is working. But then, when I go to the new "WPMU Dev" menu, where I'm supposed to log in to WPMUDev so the plugin is connecting to the hub, I have no options to log in.
All I have is this page ( https://e-xpertise.ch/demos/aj/wp-admin/admin.php?page=wpmudev) that says "Let The Games Begin" and "No account? Sign up to WPMU DEV today!"... But I don't have any login form, so I can log in to the WPMUDev account the way I did on all my other websites.
Any idea of why ? How can I log in ?
