Та страница, на которую я ссылался, была бесполезной
Я следовал инструкциям здесь: http://themesbyeris.tumblr.com/tutorial07
Сделал это
<div class="container">
<div class="main">
{block:Posts inlineMediaWidth="700" inlineNestedMediaWidth="700"}
<article class="
{block:Text}text {/block:Text}
{block:Photoset}photoset {/block:Photoset}
{block:Photo}photo {/block:Photo}
{block:RebloggedFrom}reblogged {/block:RebloggedFrom}
{block:Quote}quote {/block:Quote}
{block:Link}link {/block:Link}
{block:Chat}chat {/block:Chat}

{block:Answer}answer {/block:Answer}
{block:Date}not-page post-{PostID}
{block:Date} {MonthNumberWithZero} / {DayOfMonthWithZero} / {ShortYear} {/block:Date}
{/block:Date} {block:PermalinkPage} active exposed{/block:PermalinkPage}" {block:Date}data-post-id="{PostID}"{/block:Date} {block:SupplyLogging}data-supply-logging='{positions}'{/block:SupplyLogging}>
<div class="post-wrapper clearfix">
<header class="post-header">
{block:LikesPage}
<a class="post-blog" href="{Permalink}"><img class="blog-avatar" src="{PostBlogPortraitURL-30}" data-blog-card-username="{PostBlogName}">{PostBlogName}</a>
{/block:LikesPage}
{block:RebloggedFrom}
<a class="reblog-link" href="{ReblogParentURL}" data-blog-card-username="{ReblogParentName}"><i class="reblog_sm"></i>{ReblogParentName}</a>
{/block:RebloggedFrom}
</header>
<section class="post">
<a href="{Permalink}">{DayOfWeek}, {Year}-{MonthNumberWithZero}-{DayOfMonthWithZero} {24HourwithZero}:{Minutes}</a>
и все работало нормально.
