its your path issue, it mostly happen when you transfer your remote drupal site to your local machine and set that up, the most important part is to setup the '/tmp' path, for you must have to go to:
admin-> config -> file system ( Under Media )
Then scroll down and change or correct the path of the tmp there eg:
Temporary directory: c:/wamp/tmp // in case if you are using WAMP server
In case if you are using any other AMP client eg ( XAMPP, MAMP or whatever ) use the exact path of the tmp here and this should do the job.
Please remove the preceding / from Temporary directory (i.e. tmp/central) and try
Hope this will helps you.
