I visited your shared site and it seems the home page having page id 36 contains some unclosed HTML markup in its content which is causing this issue so to resolve the issue try deleting whole markup code from the page or setting another page as your site home page.
So what you have to do is get the actual HTML text of your image file. To do that, create a new post (you won’t actually post it), and paste the URL of the image in the description box, but make sure it’s under the “Visual” tab. After pasting the URL, switch to the “Text” tab and it should change into an HTML code. That’s what you want to paste into your “About Me” section.
So instead of pasting the URL of the image into the description box, you actually just “Add Media” directly. Select your photo, and once it uploads THEN select “Text” tab, and it should give you the code.
