After moving to a new host, i can no-longer use the IP-based login featue of this plugin. Everything worked just fine on my old host (using litespeed webserver). The new host uses apache with varnish enabled.
I have tried to make a clean install on another apache based host, but havent got any luck.
Have tried all kinds of settings and .htaccess additions to disable caching. Nothing seems to work. The website behaves just like the ip-address arent correctly set up (works on the litespeed, not the apache).
