Fix WordPress mainContentOfPage Schema Error (Genesis)

The New Google Structured Data Testing Tool Gives Error Against Genesis HTML5 Child Themes. Commenting Out Three Lines Will Fix This Issue. According to IBM , Microdata is a simple way to add structured data on the web page. It defines several attributes, such as item type and itemprop, can be placed in the HTML tag to indicate what the page is about. Microdata was introduced in 2009 by Ian Hickson, the editor of the HTML5 specification. However, the origin of this idea before long. In this guide we will fix WordPress mainContentOfPage Schema error for Genesis child themes.

Why mainContentOfPage Schema Gives Error in Genesis Child Themes?

The practical answers are two – first is Google.

From their logic :

As we are using mainContentOfPage, you probably want to have a WebPage item. But this property can not have Blog as value, it needs to be a WebPageElement. So, removing itemprop="mainContentOfPage" is the right approach. You need not to become an expert of WordPress template hierarchy. You only need to do SSH and edit a file or edit from SFTP.

Secondly, the people who are involved in the development of the paid themes, rarely has a Masters degree on science related subject – you can forget about a degree on software engineering. All together, somehow running.

If you add filter on Genesis child theme’s functions.php file, it will actually increase at least two query. One is from core of Genesis – which will direct to inject the snippet, another you added – on Genesis child theme’s functions.php file. If you comment out the function from the core of Genesis, you are decreasing one query. Only problem is that, you have to remember to do it every-time you update Genesis, till they fix it somehow.

You will get these :

Open the file in nano :

Comment it out :

Write out with ^ + O and exit nano with ^ + O. Clear W3 Total Cache’s all Cache. Test it with the new Google Structured data testing tool. You will not get any error. If you have Genesis Simple Hooks plugin installed, you can go to the filed named genesis_before_entry Hook (under Entry Hooks) and add :

You should add the values Technology and Article if it matches your niche. Else check the schema.org documentation. Again flush the cache and test. Right now, we have some errors related to JSON-LD plus our markup things are very complicated. Do not test ours, you might get confused.

Genesis like themes are not real Free Softwares, we can not see the diff for the next upgrade. So you have to manually do the works again.

Update for Genesis 2.2.6
