I have successfully installed WP and created a website but all of a sudden I cannot seem to log back into WP. The only thing I can remember altering was in the general settings area, under settings --> general. Here, in the spaces adjacent the phrase worpress address (URL) and Site address (URL), all I did was add www. and also removed /wp. WP then automatically logged me out which I managed to log back in. I then installed the 'responsive' theme. Although the website is accessible it looks a complete mess. There also appears to be no option to log back into WP. Any ideas please?
