Uploading from local to server sometime you have issue with path. The problem will be easily solved by making sure that you use relative path when include or require a file.

After making sure of that, you can upload the whole folder containing your project and our koolreport library to server.

You can upload all unzip folder which will take time, the faster way is to zip folder, upload and unzip. If you use cpanel, there is option to unzip folder.

Hope that helps.
