Recent Divi updates have made the read more and pagination links wrap onto two lines. To fix this find this section of CSS in the stylesheet:

/*Style the read more links*/

.ds-blog .et_pb_post a.more-link,
.archive #left-area a.more-link,
.search #left-area a.more-link,
.pagination a {
    font-size: 16px;
    background: #000000;
    color: #cad0d9;
    border-width: 1px !important;
    border-color: #000000;
    border-radius: 0px;
    padding: 0.3em 1em;
    font-weight: normal;
    font-style: normal;
    text-transform: uppercase;
    text-align: center !important;
    letter-spacing: 5px;
    display: table-cell;
    -webkit-transition: all 0.3s;
    transition: all 0.3s;
}

And change it to this:

/*Style the read more links*/

.ds-blog .et_pb_post a.more-link,
.archive #left-area a.more-link,
.search #left-area a.more-link,
.pagination a {
    font-size: 16px;
    background: #000000;
    color: #cad0d9;
    border-width: 1px !important;
    border-color: #000000;
    border-radius: 0px;
    padding: 0.3em 1em;
    font-weight: normal;
    font-style: normal;
    text-transform: uppercase;
    text-align: center !important;
    letter-spacing: 5px;
    display: block; /*Updated 20/02/18*/ 
    min-width: 200px; /*Added 20/02/18*/
    max-width: 200px; /*Added 20/02/18*/
    -webkit-transition: all 0.3s;
    transition: all 0.3s;
}

And then directly below this, add the following:

/*Added 20/02/18*/
.pagination a {
    max-width: 300px;
}

Applies to Bliss V1.1 and has been fixed in V1.2.
