3. Try uploading the file again in WordPress.

Note: if the upload_max_filesize size is bigger than post_max_size, then WordPress will still follow the post_max_size size, in this case I changed both to 16MB.

You can see the upload file size limit by visiting the Media> Add New page, here are the before and after results.
