There are some common errors when installing WordPress themes, but the most common is “Missing stylesheet”. This means that you are trying to install the wrong file or folder. The best thing to do is to double check that you have uploaded an installable theme zip file (it should not be the open folder or all files and documents zip).
Another common error is a white screen when you try to install a new theme. This usually means that you need to increase the server memory limit. Some hosting companies have an option for this in the main admin or cPanel, but you can always contact the hosting company's support team for help.
