Undefined method `cache_template_extension' - Not finding how to fix that

Hello I upgraded my rails to the version 2.3.2, but after restarting
my server, this error happened,

I researched in some threads and discovered that
cache_template_extensions is deprecated, but i couldn't find it in
anyway in my

code, please, can you help me to fix this issue???

Thank you.
