I apologise for this simple question. I have just installed pChart (Apache2, PHP5) and have followed all instructions on the web page - but only get a blank screen when trying to access the example files. GD and FreeType extension are enabled. Where do I start looking for the problem?

Not sure if you're still experiencing issues, but I was experiencing a similar issue after moving my project over to a new server, and discovered that the problem was with PHP memory_limit setting. Basically, PHP was crapping out when it tried to load the pDraw file, because my PHP memory_limit was set to 32MB. Upgrading that to 512MB (and restarting the server) fixed the issue.
