Hi,

We just set in plugin to override on the front end to "YES" and get blank page with error "TCPDF ERROR: Some data has already been output, can't send PDF file" when trying to generate invoice in front-end user order panel. Same issue for back-end. Do we miss some setting?

Tried with protostar template.

Hello,

It indicates that something is generating data before the plugin ; like a third party plugin which would "echo" some content.
Because of that, the lib cannot send the headers so it can't send a PDF file instead of an HTML document.
php.net/manual/en/function.header.php
You should check your template and third party plugins ; you might need to perform a bit of debug in order to know which file did send some data to the client.
