Missing Donate Button after Update

I updated Fundraising and now the button is missing. The only recent change to the site was applying updates and we had no problems receiving donations previously. My Projects are not set up as Crowdfunding Project so I can't set any start or end dates. But all my projects appear as "Time's up". Please resolve
