There is a simple fix in the event that your website pages display this notice in the comment section:
To solve this, you need to change the global page options – namely, navigate to Theme Options > Page, locate the Show Comments option and set it to No, so that the comments are prevented from being shown.
After this, Save the change you made, clear the cache and refresh your website in the browser.
In case this notification appears on a certain number of your website pages only, you need to check the options for that individual page, as opposed to global Page options. All you should do is located one of the pages in question and check if the Show Comments is set to No.
If this option is set to No in both the global page options and the options for a specific page as well, the notice will not be displayed anymore.
It’s important to note that individual page options always override options set for the entire website in global options. This gives you the possibility to customize and style individual pages differently.
