Error: onApplicationStart: component [org.mangoblog.Mango] has no function with name [GETDATAACCESSFACTORY]
I got this error once I've installed MangoBlog. I've already checked there is "GETDATAACCESSFACTORY" function in components/mango.cfc file.
PS: I've installed it on Railo.
Looks like this is a plug-in you should have installed but don't for some reason. I'd compare a fresh downloaded version with what's on the webroot. Beyond Compare will do it for you in a blink
I helped ppshein on the Mango Blog forums, where he also posted this issue. It turns out that all he had to do was restart his CFML App Server (Railo).
