I added new templates to the themes folder and now I can't see my blog. I tried to update one of the themes on my blog and then my blog's theme reverted back to the default template. Then when I continued to try to upload the files to a new template that's when I couldn't see my blog at all. I can't even login to the admin section. Does anyone know of a file that I will need to upload that will at least let me see my blog again? Or what files will I need to keep so that if I have to reinstall the entire WordPress directory, I will not lose my posts and comments?
