On installing JpGraph, I get:
JpGraph Error General PHP error : Non-static method DB::isError() should not be called statically
This is on Linux/X Windows, with a basically working JpGraph installation (working except for fonts).
Oddly, the php documentation for isError says "Note: This function should be called statically.". But changing it to a non-static reference changes the error message to:
JpGraph Error General PHP error : Non-static method DB::connect() should not be called statically

A php screwup that affects lots of projects.
