Page Not Found error - and another bug

[#1]

This is an interesting one. I am logged in when this happens!

 

Yes, I did follow an old link, the link to the old SMF main forum page as it happens
http://community.plus.net/forum/index.php

The next stupid things are that the Link Locations for the 3 suggested locations in the error message all show as http not https, yet clicking on each does correctly end up on the relevant https page - and it was showing I was logged in - which I was - remember!
So why didn't my clicking on my old link end up on a https error message page?

And more interestingly, when I click on the Browse button there on the main Toolbar, I get

A BLANK Browse menu!

I wonder how inter-related this bug/error is with all the other obscure errors we see from time to time, such as -

https://community.plus.net/t5/Community-Site-Feedback/Authentication-error-on-community-are-you-affe...

To complete the picture, this is repeatable using both Pale Moon or Firefox (Forum software 16.5-release r309149)

Looks like a redirect has stopped working.

As for the browse menu, I can see the menu in the code but for some reason its being obscured when on the 'page not found' template.

@LouisaMartin, can you inform Lithium about this please? Let them know that the redirect has stopped working for http://community.plus.net/forum/index.php and that the browse menu isn't rendering correctly when on the error page.

I've raised this to Lithium #00121129
