No sites on dashboard, but yes on sites tab

I installed a new MainWP site for a client, added 4 websites and… nothing happens on the dashboard. Not a single item is shown there and the rest of the tabs BUT, if i enter to the sites tab i can see the 4 websites and how many updates everyone needs.

I don’t know wich plugin can block the MainWP behaviour but is not WP Super Cache (i tried deactivating some)

In the dashboard it says there’s zero sites connected wich is incorrect when i see the sites section, what can i do? some ideas?

BTW: i have a different site with MainWP without problem, working fine and managing 15+ sites

thanks everyone!
