thank you.

you have start/end tag mismatches on site. causes layout thrown out of alignment.
close div tag before insertion of page break or read more in article.

code: select all

<div>
<page break />
</div>

this invalid close tag not shown on page.

this ok

code: select all

<div></div>
<page break />
<div></div>
