I built a new wordpress site over an old one. I deleted all the folders before rebuilding the site with a new name, old url. The previous site had wordpress installed in another directory other than the root. The root directory had another folder, which previously was seen first when the website was accessed in the browser. I deleted the old wordpress and the folder in the root directory before installing the new wordpress in the root directory. I am still getting the old folder's contents accessed when the url is typed into the browser and not wordpress. Wordpress forum suggested removing the url from the cookies in the options, privacy section of Firefox, which I did. Now I can no longer access the website, either the wrong folder or the new wordpress site. I get a white screen. Can you help?
