Two commas are added in the “category -links” class, right above the excerpt. Do you happen to know how I can remove them ?

Hi,
To resolve this issue, you can add the following code to the style.css file:

.archive .content-inner .cat-links a {
    color: #666 !important;
    display: inline-block !important;
    padding: 0px !important;
}

Hope this helps !
