Hello debbie.marshall, the first link is, for me, an 404 error

the second loads fine, try to clear both cookies and the cache and check it again. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

1. Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.

3. Now, click the arrow next to Details to toggle the Details list active.
4. From the details list, check Cache and Cookies and uncheck everything else.
5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

Google Chrome also report this certificate as being revoked.

The server's security certificate is revoked!
You attempted to reach beta.mypeopleandplaces.com, but the certificate that the server presented has been revoked by its issuer. This means that the security credentials the server presented absolutely should not be trusted. You may be communicating with an attacker.

So you will have to contact the issuer of the certificate (DigiCert High Assurance CA-3) and ask them to look into this.
You can do nothing about this apart from disabling OCSP temporarily, which is never a good option and should be considered which great care as this poses a risk.
