How to Fix Publisher Error, dateModified and datePublished
In the Structured Data Testing Tool you can test or check the data information for your blog. If there is a sign of error, it means that you have not entered the correct information. There are various errors in the Structured Data Testing Tool. And here is how to fix the Structured Data Testing Tool on the blog.
Error Headline "A value for headline field is required"
If you find the message "A value for headline field is required" when checking the data structure, then you can do the method below to fix it.
Look for the code below
<h1 class='post-title entry-title' itemprop='name'>
<h2 class='post-title entry-title' itemprop='name'>
<h3 class='post-title entry-title' itemprop='name'>And replace with headlines
<h1 class='post-title entry-title' itemprop='headline'>
<h2 class='post-title entry-title' itemprop='headline'>
<h3 class='post-title entry-title' itemprop='headline'>Maybe h1 can be more than 1, as well as h2 and h3. So if there is itemprop ='name' behind it just replace it with itemprop ='headline'.
Error Image, Publisher and MainEntityOfPage
If you see an error code "A value for image field is required" and the error code "A value for publisher field is required" fix it by searching for the code below.
<article class='post hentry' itemprop='blogPost' itemscope='itemscope' itemtype='http://schema.org/BlogPosting'>And after finding it, put the following code under the code
<div itemType='https://schema.org/WebPage' itemprop='mainEntityOfPage' itemscope='itemscope'/>

<a class='updated' expr:href='data:post.url' rel='bookmark' title='permanent link'><abbr class='updated' expr:title='data:post.timestampISO8601' itemprop='datePublished'><data:post.timestamp/></abbr></a>And change by adding the code <span itemprop='dateModified'> at the beginning and at the end </span>, which will be like this
<span itemprop='dateModified'>
<a class='updated' expr:href='data:post.url' rel='bookmark' title='permanent link'><abbr class='updated' expr:title='data:post.timestampISO8601' itemprop='datePublished'><data:post.timestamp/></abbr></a>
