Error: SyntaxError:

Can you please check now… I couldn’t find any issue with the file upload functionality in your site

If it’s the same error I had, that’s because of a problem of the plugin.
clearstatcache only accepts two parameters from PHP>5.3.0 on.

So UploadHandler.php should read:

protected function get_file_size($file_path, $clear_stat_cache = false) {
        if ($clear_stat_cache) {
            if (version_compare(PHP_VERSION, '5.3.0') >= 0)
              clearstatcache(true, $file_path);
            else
              clearstatcache();
        }
        return $this->fix_integer_overflow(filesize($file_path));

    }
