“HTML minified” is showing at the bottom of the page source. Your site has something which is compressing the html. This makes it less human-readable and so harder to work on.
Yes, your image does show stars, so the star font must be loaded on admin pages. However its not loaded on front side pages, hence the SSSSS. Fortunately fontawesome is loaded front side, so we can use that. The star symbols have a different code in fontawesome, so we need to change them as well.
Try this custom css:
.star-rating:before,
.star-rating span:before {
font-family: fontawesome !important;
content: "\f005\f005\f005\f005\f005" !important;
}
Custom css is best entered at:
Dashboard > Appearance > Customise > Additional CSS
This fix always gives 5 stars, ie it is not dependant on actual reviews.
I think it likely this is a theme fault. You would need to temporarily deactivate all other plugins to be able to rule them out and check to be sure. If it is a theme fault, www.ads-software.com can’t support non-www.ads-software.com themes, so you’ll need to approach your theme’s support service for a better and permanent fix.
