And re: my first problem (will not log in with IE) I now see in the httpd error log I get the following error every time:
[Fri Nov 20 14:08:13 2015] [error] [client 10.0.0.116] File does not exist: /var/www/html/ucp/assets/js/html5shiv.js, referer: http://pbx.XXXXXXXXX/ucp/
Is there a file I should have somewhere that is missing? Where can I get this file to put there, assuming that will fix the problem?
