fix: PHP post_max_size set higher than upload_max_filesize

The maximum size of file upload depends on both variables and
post_max_size should be set higher.  70M is appropriate because
upload_max_filesize is 64M and the 6M difference is the same as when the
values are at their defaults (2M and 8M).
