I am using CakePHP 4.2, and Upload plugin.

The app can upload small files OK, but when I upload 30 MB file, it failed and gives error message: `CSRF token from either the request body or request headers did not match or is missing`

Is there anything to do with multi-part form upload?  
How to fix this ?

Thank you very much

What are your `post_max_size` and `upload_max_filesize` ini values?

Thank you very much Zuluru,

I did changed `Upload_max_filesize` to 512 MB, but forgot about the `post_max_size`. My bad.

It works fine now. Thanks again.
