Expired SSL cert for deeplearning.mit.edu and potential css issues.

[steve-a-jones]

Hello,

Just wanted to let you know that the SSL cert for deeplearning.mit.edu expired on 11/15/2024. The page itself does not appear to render correctly as well. Not sure if this a css issue, but when you visit the site there is a visible error from the backing php script on the wordpress server:

Notice: Undefined index: title in /var/www/lex_fridman/wordpress/wp-content/themes/twentytwelve-child/grid-vid.php on line 68

I'm just starting to dive in to these lectures (thank you for publishing them along with this repo) and wanted to give you heads up about the state of the site.
