Do you experience Microdata disappears from your pages and posts?
What makes Wordpress remove Microdata data?
It happens within Classic Editor or in Block Editor in sections managed by Classic Editor. I experienced that after saving my content.
It happens because the editor knows which attributes are used in standard HTML pages and it encounters new and unknown attributes. The editor decides that they are not needed and removes them.
Partial solution
One part of the solution is written in this page.
Complete solution
So here are instructions to solve the whole problem:
- Install this plugin - Advanced TinyMCE Configuration Plugin
- Dont worry that the plugin is old. It works flowlessly with Wordpress 6.2.x. I guess it would work after years because there is almost no changes in Classical editor.
- Enter this option name: extended_valid_elements
- The option value you want to add: @[itemscope|itemtype|itemid|itemprop|content],div,span,h1,h2,h2,h4,h5,h6time[datetime]
