What is the common issue with uploading files using Plupload on XAMPP?

When uploading files using Plupload on XAMPP, a common issue is that the file size limit set in the PHP configuration may be too low, causing uploads to fail. To solve this issue, you can increase the `upload_max_filesize` and `post_max_size` values in your php.ini file to accommodate larger file uploads.

// Increase file size limit in php.ini
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '25M');
