Hi,
As I expected, this issue comes from the CSS of your template.
Remove that code:
.art-postcontent ul>li, .art-post ul>li, .art-textblock ul>li {
overflow-x: visible;
overflow-y: hidden;
}
from the file /templates/sage1_v1/css/template.css and it will display properly.
Please contact your template provider for such display issues in the future.
Regarding paypal express, yes you're supposed to open a new thread for unrelated questions.
However, it's probable that the issue is with how you've configured the payment method. Make sure that its button display settings are activated and you should find the paypal express button on the cart block.
