Ok so...
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', true);
all do nothing... cleared cache, used a machine that has never been to the site, no verbose error, no log file, no nothing.
I find yes i can upload tiny tiny files like 53k (useless)
php.ini all limits set to 64MB
.htaccess does not exist in this build yet so no problem there.
Next idea?
