Answer 1

The command sudo chmod -R 777 cakephp/app/tmp only made tmp writable, you should make cache and it's subdirectories writable as well, otherwise Cake can't write the cache files to the cache directory in tmp.

So, these directories should be writable:

cakephp/app/tmp/cache
cakephp/app/tmp/cache/persistent
cakephp/app/tmp/cache/models

Make sure the log directory is writable as well: cakephp/app/tmp/logs.
