You created a reusable block which contains schema markup, but now this block cannot be found? What schema format are you using? In what kind of block? Some formats are not fully compatible with block content. It may require a custom block or shortcode to properly embed schema markup in page content.
FWIW, most SEO plugins that provide structured data add it via an action hook based on added fields on the edit screen, completely avoiding the use of blocks. This sort of trouble might be why they do it that way 🙂
Hi thanks for your answer, Im using Guttenberg blocks and I asumme every time you add the SEO plugin by default the shema markup will show up when try to add the block to a page and you type the name of the block in this case “yoast” or “rank math”.
How structured data is managed will vary by plugin. I’m not aware of one that utilizes blocks for this, but it’s conceivable a custom block would be added. There’d be no way to predict the name, though the plugin name is a reasonable guess. If you have difficulty, I recommend asking for help in the dedicated support forum of whichever plugin you are using.
Looks like one of the plug-ins was blocking rank math, went and disable all of them and then activating one by one after that we realized what block was the problem.
