I'm just trying to get the graphs working in mantis for the first time but I've come up against the following error when trying to view a graph image directly.
The jpgraph test suite works fine however.Fatal error: Class 'Graph' not found in D:\web\xampp\htdocs\mantis\core\graph_api.php on line 56
Specs:
Mantis 1.0.1
PHP 5.1.1
Windows XP
jpgraph 1.20.3
Any ideas?
