You will get prompted with the message to enter your library path location if you do not have upload checked when building your Flipbook.
You can either:
Use the built-in FTP uploader in Live Tiles.
You are able to enter your ftp details and setup your upload profile by clicking on add under the upload panel in the output tab. Once you have setup the upload profile you then should be able to build/upload online.
Upload your issue folder to your web server manually
If you don’t wish to use the built-in FTP uploader in Live Tiles, you can simply generate the issue folder locally on your computer and then upload the issue folder to your web server separately using an FTP client such as Filezilla. You can choose to only create the local issue folder if you un-check the “Upload” option on the Content tab of Live Tiles. You would just need to drag and drop the entire issue folder that the application creates to the remote directory on your server.
If you have problems setting this up, please send us your server’s FTP details and we can attempt to make a step-by-step tutorial for you to follow to get it setup successfully. If you’re not sure about your server’s FTP details, your webmaster or hosting provider should be able to assist with retrieving those.
