PAGE MISMATCH ERROR

Hi, I have a message in my Google search console that says
New Accelerated Mobile Pages issue detected for site https://infobunny.com/March 8, 2018
To owner of https://infobunny.com/,

Major content mismatch

I have in fact 4 pages that S console says have errors and they are all to do with the forum that I have that is run on bbpress.

Any ideas how to fix this?
Thanks in advance
