file path error

[grjan7]

Hi, I came across file path error in doRequest.php.

Warning: unlink(/var/www/html\uploads\test.json): No such file or directory in /var/www/html/doRequest.php on line 133
{"response":"","statusCode":"Unknown error occurred (HTTP status 404)"}

Note: the file path for unlink( DIR.'\'.$uploadfile) has mixed slashes.
