The error happens when warming up caches and is in full:

I've seen this error before and got around it but can't for the life of me remember how nor can I find the notes I'm sure I made about it. Driving me crazy. What is weird is that the live server gets this error but not my dev server, which is a copy of the live one. The fpdf.php is there.
Thanks
