When I enable GraphVizPlugin on 11.3 all my other wiki macros break.. So for existence, on the wiki index page, I only see... {{{ Error: Macro TitleIndex(format=group,min=4) failed coercing to Unicode: need string or buffer, NoneType found }}} After I disable it under admin, macros work fine again. I've also successfully run GraphVizPlugin on previous 0.11.x installations. Details of my setup include OS X 10.5.5 with the stock Apache 2.2.9 and Python 2.5.1 ... mod_wsgi 2.3 and ''dot'' installed to '/usr/local/bin'" defect closed high GraphvizPlugin blocker worksforme needinfo 0.11
