Wordpress wp-admin/import.php blank screen after ACME cert installed


i have ACME Cert working now. Qualys Lab SSL Test show A+
but wordpress wp-admin/import.php fail to work now…

i am getting a BLANK screen for all import options in wordpress gui.
up the CPU n MEM, nothing happened
turn on debug = true on wp-config.php. no error shows up.

any advice what is wrong here.

fyi wordpress is running on top of nginx



this is the details of the wordpress phpinfo.php output

ubuntu16.04-wordpress4.5.2-nginx1.10.0-php7.0-fpm-phpinfo.txt (93.8 KB)


this is really ODD…
let the machine sit there overnight, this morning everything starts working…
will test another instance…


Could have been something in the browser cache, and either clearing the cache manually (or leaving it overnight, so it clears) corrects things.
