thanks for your reply. No I have not changed anything, there is one other person who posts to the blog, and she first noted the problem, and it is possible that she altered something in the admin area, without being aware of it.
I have continued to search through posts here and noticed some people posting about plugins. I renamed the plugins folder and the problem was unchanged – front end of the blog stayed online, but I still can’t login at all.
hope you may have some ideas, thanks
