Error: Missing required field "updated"

[AlirezaHamidian]

In my WordPress blog, there are pages for tags,categories,... like :

https://www.abc.com/blog/**category**/how-to-cook-something/

On these pages I am getting the following error:

Error: Missing required field "updated"

So far I have 39 if these errors.

Please let me know if this is an important issue to pay attention to? If yes, how I can fix it?

Thanks Everyone

Hi Armin,

Is there any more information you can provide here? With what kind of tool did you check the page? That would give a better information on where the error is coming from. For now I suspect some markup related to Schema.org is missing.

Hi Martijn,

I found them in webmaster>Search appearance>Structured date>hatom and when you go to live test data you see the mentioned error.

Any thoughts on it?
