A very common issue that occurs with users new to installing WordPress themes is a “Broken theme and/or stylesheets missing” error message being displayed when trying to upload or activate the theme. This error message does not mean that the ListingPro theme you have purchased is broken, it simply means it has been uploaded incorrectly
If you have downloaded all the files, you have to unzip it and select the correct file (ex. listingpro.zip).
