Post images wont align centrally

Hello @kerryvillers

The images is contained within a span which does indeed have an .aligncenter class.

However, that class does not have any alignment properties in your CSS

There are many ways to fix this.

The simplest way in your case is to add the following CSS code in the Custom CSS editor in the WordPress customizer – since you’re using WordPress 4.7

.aligncenter {
    text-align: center;
}
