After switching to HTTPS, elements with HTTP appeared in the page code. In templates did not find them...

<li id='cCreate'>
				<a href='#elCreateNew_menu' id='elCreateNew' data-ipsTooltip data-ipsMenu title='Новая публикация'>
					<strong><i class='fa fa-plus'></i>  Создать</strong> <i class='fa fa-caret-down'></i>
				</a>
				<div id='elCreateNew_menu' class='ipsMenu ipsMenu_auto ipsHide'>
					<ul>
						
							<li class="ipsMenu_item">
								<a href="http://xxxxxxxxxxxxx/modcp/announcements/?action=create"

<li class="ipsMenu_item">
								<a href="http://xxxxxxxxxxxxxxxxx/submit/"

In my opinion this bugs 🙂 What to do? 🙂

You have to rebuild the cache. ACP > System > Support > Something isn't working correctly

No bug. Template links should be converted automatically. If they are not, you need to clear the cache to refresh the links. 

The schema.org links do not load external resources. They don’t need to be updated to https. In fact, no outgoing links need to be changed. 

Oops 🙂 I still made a couple of changes to the template for schema.org ahhh! Forcibly updated the browser cache and now everything is fine! Thank you! 🙂
