I'm testing the Page Security plugin for my latest client site. When there is no user logged in and I try to click through to a secure page, I do not get a login nor any expected message. Instead I get a 500 Internal Server Error with the message "There is a problem with the resource you are looking for, and it cannot be displayed."
The page displays correctly if a user is logged in.
Site is running on Microsoft IIS/7.0
Page Security 1.5.8
I have tried disabling plugins to try to track conflicts but have not had any positive results.
I have also tried setting permalinks back to default with no effect.
Site URL is http://kaurifunds.dev.boldhorizon.co.nz
Protected page is http://kaurifunds.dev.boldhorizon.co.nz/investor-centre/
Any suggestions for trouble-shooting or resolution gratefully received.
