If an upload fails because the file is too large, you can raise the PHP upload limit in cPanel. This guide explains which settings control it and how to change them with the MultiPHP INI Editor.
The settings involved #
- upload_max_filesize: the largest single file you can upload.
- post_max_size: the total submission size, which must be at least as large as the upload.
- max_execution_time: gives big uploads time to finish.
Changing the limit #
- Log in to cPanel.
- In the Software section, open MultiPHP INI Editor.
- Select your domain in Basic Mode.
- Raise upload_max_filesize and post_max_size to the size you need.
- Click Apply.
Verifying the change #
In WordPress, check Media > Add New, which shows the maximum upload size. Or create a PHP info page to confirm the new values. Try your upload again once applied.
Troubleshooting #
- Limit unchanged: confirm the correct domain and PHP version, and clear caching.
- Still failing: raise post_max_size and max_execution_time too.
