Please help, I have just installed wordpress in my new host and have uploaded some of my themes but they all won't show up in my admin panel in wordpress and saying that "Stylesheet is missing." I have uploaded twice style.css files and still the same problem. Is there anything to be done with my host settings or something?
You might not be uploading them properly. Some themes are zipped that the actual theme folder is inside the zip generated folder. Ensure that you are uploading the correct folder. Incase it still doesn't work, contact the developer of the theme.
