I fixed that link. Can you check/confirm that you did follow the advice there?
As to the bullet points. This theme CSS file:
https://www.hifi-advice.com/blog/wp-content/themes/theblog/style.css
On line 861 has this CSS, which is causing them:
.body-content ul > li:before {
content: "\f105";
font-family: "FontAwesome";
position: absolute;
left: 0;
top: 5px;
line-height: 1;
}
Add this custom CSS to the theme customizer to fix this:
.body-content .searchandfilter ul > li:before {
content: none;
}
Once I have the answer to the first part of this reply, I need to see the content of the results.php file, IF you have modified it? If you did not modify it, do you have a Related Posts plugin installed (which one), as it may be automatically adding that content after the post excerpt?
