Problem uploading themes!

When i try to upload a theme it says that it has installed succesively and them this:
Warning: fopen(/home4/bitsfoub/public_html/gamesinfoworld/wp-content/themes/shiwordreverse/style.css) [function.fopen]: failed to open stream: No such file or directory in /home4/bitsfoub/public_html/gamesinfoworld/wp-includes/functions.php on line 4339

Warning: fread(): supplied argument is not a valid stream resource in /home4/bitsfoub/public_html/gamesinfoworld/wp-includes/functions.php on line 4342

Warning: fclose(): supplied argument is not a valid stream resource in /home4/bitsfoub/public_html/gamesinfoworld/wp-includes/functions.php on line 4345

and when i go into the code it says this:

function get_file_data( $file, $default_headers, $context = ” ) {
// We don’t need to write to the file, so just open for reading.
$fp = fopen( $file, ‘r’ );

// Pull only the first 8kiB of the file in.
$file_data = fread( $fp, 8192 );

// PHP will close file handle, but we are good citizens.
fclose( $fp );

How can i sort this.
