Where can I find FPDF? "FPDF error: Some data has already been output..."

Where is FPDF? I use Wordpress and Go Daddy, I am trying to use this WooCommerce PDF Watermark, and I am getting a fatal error that causes the watermark not to be visible.
The error is below, how can I fix this?

The server hosting your WordPress site must have the PHP class FPDF installed.
It is generating PDF files free of charge.
That class is one of the requirements of the Plugin "WooCommerce PDF Watermark".
See if you can install it at Go Daddy.
For instance by making FPDF a Composer requirement, if you can use Composer with your hosting package.

Any help, will be greatly appreciated.
Thanks.
P.S. - the theme used is called newspaper and is by tagdiv.

Updating the TDCloud Plugin Plugin should do the job. Or downloading a fresh copy and overwrite the files.

It appears you're either missing a plugin or it has been deactivated.
From looking at the error message and searching for unique terms, I guess you have the Newspaper-Theme installed. Their website mentions "tagDiv Mobile theme" as an optional plugin. Maybe your theme has been modified so that it's no longer optional but required?
See if that plugin is installed and activated.

I have a similar problem. The problem was solved after deactivating plugin "WooCommerce Auctions Pro"
