Can't figure out what broke with my TCMS Blog

Just noticed a blog I have running for a client isn't working exactly as expected.

The date of each blog post is displaying more content than I have set up for (only wanting the date).

Also, the navigation at the top doesn't work and my footer has disappeared.

This is the current error log:

[26-Mar-2024 21:46:12 UTC] PHP Fatal error: Uncaught Error: Class "IntlDateFormatter" not found in /home/lnvhwkbs/domains/hayward.org/rw_common/plugins/stacks/total-cms/TotalCMS/Component/Blog.php:809

#2 {main}

Any ideas what I should do?
