I have tested this item ✅ successfully on 9c796ff

If I apply this patch in the file default_items.php (at line 101) then I get another error and the original error is still there: "Duplicate values for itemListElement.url are not allowed."

@EJBJane

I can't reproduce your find with core Joomla.

• Do you use an template override for file components/com_tags/views/tag/tmpl/default_items.php ?
  You should not for testing this pr.

• Did you follow the testing instructions exactly? Same menu item type and so on?
  If not: What are the differences between your menu item and my screenshot above?

• Can you provide the link to your page where I can see the error?

I did have an override.. (very embarrassing sorry)
Your patch absolutely did work!

maybe outside of the scope of this pr....
btw
i still get an error

@alikon
Tested yesterday after removing (temporary) my .htaccess (otherwise not possible) :-)
Just an idea: Code review shows:

<li class="cat-list-row0 clearfix" itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem"> <h3 itemprop="name"> <a href="/hstompers/index.php/testg" itemprop="url"> TestG </a> </h3>

your line is without /menue ?

<a href="/index.php/" itemprop="url">

Your patch absolutely did work!

@alikon

("Devi specificare un valore por il campo url" = "You must specify a value of the url field")

Your find is outside of the scope of this pr and I can't reproduce it. When I test a Tagged Items page that contains the following code (similiar to your snippet; same url "/index.php" for first item) I see no errors.

<ul class="category list-striped" itemscope itemtype="http://schema.org/ItemList">
    <li class="cat-list-row0 clearfix" itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">
	   <h3 itemprop="name">
		  <a href="/index.php" itemprop="url">
			 00000 GHSVS Berlin Kreuzkölln
		  </a>
	   </h3>
	   <span class="tag-body" itemprop="description">
	   <p>Blah blah</p>
	   </span>
	   <meta itemprop="position" content="1">
    </li>

TBH: If it wouldn't be a B\C break I would propose to remove at least the ItemList microdata from this view ;-)
