I installed the Inline Account Hierarchy package on the App Exchange a while back and some how it is now broken. It's the second time this has happened. Not sure how it broke becuase I haven't changed anything in SFDC. Funny thing is as the administrator, I can see it. It's only non-administrator who now see a broken Inline Account Hierarchy tree. All people can see now is the SFDC
Any advice on how to fix this without un-installing the package and re-installing it again?
