If the image is being generated but not displayed, the problem is almost certainly with the $PmGraphVizCacheDirUrl setting somehow. In this case, I suspect you meant to use $FarmPubDirUrl instead of $FarmPubUrl, since PmWiki doesn't have a $FarmPubUrl: $PmGraphVizCacheDirUrl = "$FarmPubDirUrl/pmgraphviz"; But more than that, if you're using $FarmPubDirUrl you need to make sure it is initialized before you use it. PmWiki doesn't set a value for $FarmPubDirUrl until after configuration files have been loaded. Even better, if you aren't using farms, then just leave these variables unset so that you get the default values. Pm P.S.: Yes, it appears that the documentation inside of pmgraphviz.php is incorrect and specifies $FarmPubUrl instead of $FarmPubDirUrl. _______________________________________________ pmwiki-users mailing list [email protected] http://www.pmichaud.com/mailman/listinfo/pmwiki-users
