Smart Slider is uploaded to the wp-content\plugins\ folder, but doesn't show up in Plugins list

Error

• Simple installation failed, and the Upload through ftp method followed it, by uploading the files through ftp, but it doesn't show up in the back-end Plugins list.

Solution

This can happen, if your server is misconfigured, and the files and folders you uploaded don't have php reading permissions. You should change all of your folders' permissions to 755, and the files' permissions to 644. You can do this for example with FileZilla. Also this is a very basic thing you should have, so you might want to consider moving to another host instead.
