I’d be grateful for any comments from users who succeeded in installing the GraphViz extension for a WikiMedia One-Click installation. I’ve followed the installation instructions carefully, and while my wiki pages are parsing GraphViz content, they aren’t returning any graphics:
Some examples I try produce an error in line 420 of GraphViz.php, to the effect that no such file is found (in the image folder). Other examples give no errors. I have the “info” option enabled, and the directories all look valid, but the image folder is in fact empty.
Is this a configuration issue, or a problem with compatibility between the extension and the latest version of MediaWiki?
Thanks in advance for any input.
