I was logged into my site at http://www.vadirectory.net/wp-admin and was entering a new member into the Add Member section of the wishlist plugin of my site. As soon as I submitted the new member I was logged out of my website and can no longer login. It doesn't recognise my username or my email address. I have been using this plugin for 2 years with no previous problems and have nearly 200 members on the website.
I have no idea if this is related to the plugin, or a problem with WordPress, or my server, so I'm trying all three, to find out how to get back into my site. Are you able to advise please?
