OK. So change to setting less than or equal to your php.ini setting for
upload_max_filesize which must be >= than
post_max_size integer. (Reference:
PHP.net Reference)
My php.ini is set to 8M by default for both
upload_max_filesize and
post_max_size integer. File sizes larger than that, say 12M, I would need to change both to 12M at least. Trade off would be larger files in storage and slower browser loading speeds.
Got it.
