Forum: Radiant CMS I have this problem when i want to edit some pages!

I have this (undefined method `include?' for nil:NilClass) when i
tried to edit some pages.
Also, I have (undefined method `include?' ) when i tried to see the
pages! some content are displayed and else throw this error!

I can handle it when I touch tmp/restart.txt...

But I want to restart the app when this error came!! any solution???

I got it fixed when I remove will_paginate 2.3.15 .. seems radiant
0.9.1 crashes with this gem! (sometimes)

We require that gem, so it's not likely that that is the actual problem.
What gems do you have in your environment? And what extensions and
plugins do you have in your app?
