Cannot generate/email PDF from quote

I have just created my first PDF Template in order to export my quotes as PDFs but as soon as I click on “Print as PDF” or “Email PDF” I get to a blank page and get error 500. I see that this is an issue that has happened before and I have tried the different solutions stated in the forums but I’ve had no luck.

I am currently on SuiteCRM Version 7.7.8 Sugar Version 6.5.24 (Build 509).

I hope you can help.
Thanks

Is there anything in your php log?
