Plugins were updating when I acc go to another page. Now can’t update plugin.

Hi,

I was doing a mass plugin updating when I accidentally click a link within the page that goes to another page.

So now, The updates are gone, the remaining ones when I try to click update, it says

Plugin Update: Failed

How can I at least restore the previous ones or make this work?

The page I need help with: [log in to see the link]
