Undefined method `output_buffer=' for <Page>

Hello

I am currently in the process of getting a cient’s Radiant site that was
began earlier this year working locally on my machine, with the 0.8.1
version of Radiant.

I have hit an obstacle in the form of the error: undefined method
`output_buffer=’ for Page:...

If anyone can help it would be gratefully received … the only info I
can find on this error seems to be to do with RSpec, but I find no clues
in the error trace leading to rspec.

Thanks for your time.

error trace below:

NoMethodError in SiteController#show_page

undefined method `output_buffer=’ for #Page:0x227b47c
