PDFs Have Suddenly Stopped Displaying

[sunshinelock]

Some pages show an error. Other pages show a completely blank html page. Others show a blank pdf page. But none of my pdfs want to print.

Is there some sort of debugging script I can run?

I've been on webERP for 10 years now and can't print any statements or invoices. I just cannot run my business like this.

The invoices I can get to print html, okay. But I have no idea who owes me for March, and no statements have gone out April 1st. So this is starting to cost me some revenue at this point.
