A common issue that users normally encounter when installing a WordPress theme is a “Broken theme and/or style.css stylesheets is missing” message, particularly if users are new to this process. The error message will be displayed while trying to upload or activate the theme. This does not mean that the theme is broken, but simply means that users are uploading the wrong file.
One of the reasons you may receive this error is if you have uploaded the incorrect file. You have 2 options for downloading your theme.
- Installable WordPress file only
- All files and documentation (full zip folder). You will need to extract and locate the installable WordPress file.
Please make sure you are uploading only the installable theme which is called NameOf Theme.zip. If you upload ALL these files you will receive an error.
