Hi guys I have Pie register Version 3.0.6 installed on several sites and I am having the same problem on each of them.
When I go to the blog page of either of the sites and find the meta widget area which looks similar to this
and run my mouse over the Log in link I get a link like the one below
If I click the link I get
You don’t have permission to access /sitename-login/ on this server.
Apache/2.4.7 (Ubuntu) Server at sitename.com.au Port 443
If I deactivate Pie Register on either site the Log in link starts to work again as expected.
