This is most strange. I managed to get logged into the wiki, but I had to do it in firefox via a search and go direct to the wiki and use the log in panel that's in the middle of the page. Now I appear to be permanently logged in.
I can go to wiki pages and click edit, but when I try and save a page I get the message ...
Sorry! We could not process your edit due to a loss of session data. Please try again. If it still does not work, try logging out and logging back in.
I can't see an option to log out of the wiki and if I use any of the menu buttons I appear to be logged out, but if I close the window, search biopowered and go to the wiki again I'm still logged in.
I previously thought the main page looked different, but couldn't work out how ... now I realise that the left hand tool bar that contained all the links to "Special pages", "Recent changes", "Upload files" etc. is missing.
Although we can view the wiki we don't appear to be able to do any more than that.
