Installation problems - Joomla
– Error installing component
– There was an error uploading this file to the server.
Unable to find installer package
If you can’t install the Smart Slider, then turn on the error reporting the same way, as it is written at the blank page part. Then try to install the Smart Slider again, and it might write out an error, which could tell you what is the problem. In most cases it’s an upload file size limitation, which can be solved by installing it from directory instead. If that doesn’t work, then upload your Smart Slider’s zip into your website, and try out the installation from url too.
