I would suggest to have your website compatible with https protocol. This will bring more credibility to your website and besides it's for your publishers security.
I have purchased cert but i have to migrate to another hosting. I think it will be done in this week.However, there is no sensitive data in service. Hacker can't do anything except claim new sites.
Good thing that you're doing it very quick. Kudos to you and good luck to your business.
