As @JuergenAuer said, you should ask Wix to know what is going on with that pretty old cert because your site is using an old cert right now but you, wix or someone else have issued a certificate covering
www.jicbmf.com and it is still valid.
CRT ID CERT TYPE DOMAIN (CN) VALID FROM VALID TO EXPIRES IN SANs
1044544118 Final cert jicbmf.com 2018-Dec-20 11:09 UTC 2019-Mar-20 11:09 UTC 68 days jicbmf.com
You could try to disable and enable again https on your wix control panel https://support.wix.com/en/article/enabling-https-for-your-wix-site and if that doesn’t work, you should contact Wix, they should be able to help you to solve this issue.
Cheers and good luck,
