Updated: 28 September 2026 · Applies to: cPanel & WHM 138 (Jupiter theme)
Two PHP settings limit uploads: upload_max_filesize (the largest single file) and post_max_size (the whole form submission, which must be at least as large).
In cPanel
- Log in to cPanel (for example at
https://yourdomain.com:2083, or from the Ucartz client area). - Open Software › MultiPHP INI Editor, choose Basic Mode and select the domain.
- Set upload_max_filesize, for example
64M. - Set post_max_size to the same or a larger value, for example
70M. - Click Apply.
On CloudLinux servers, use Software › Select PHP Version › Options. Check the result in your application (WordPress shows the limit on the Media › Add New page).
Tip: For very large files, such as videos or backups, upload over FTP instead of through a web form.
