It’s important to keep in mind that there is often a difference between an item that is broken versus an error message.
Error messages could be related to an incorrect setup, configuration or software and as a result, the item is not working, eg. - missing style.css stylesheet.
If you are having a problem with an item, we encourage you to read and search the item comments. Someone else may have experienced the same problem, and your answer may be found in the comments to help you get the item working.
