I have new instance in AWS. I have make var/www directory using PuTTy. I have upload all file to var/www/html directory. When i open IP Public Instance in Web Browser there are
Warning: _cake_core_ cache was unable to write 'cake_dev_id' to File cache in /var/www/html/lib/Cake/Cache/Cache.php on line 322
Warning: /var/www/html/app/tmp/cache/persistent/ is not writable in /var/www/html/lib/Cake/Cache/Engine/FileEngine.php on line 384
The first two warning mostly come when there is no 777 permissions to tmp, log so please assure that you have set permissions 777 to tmp and log.
The second error mostly arise because of incompatibility hopefully you have followed the log for that.
