Hi,
For some reason, I thought it would be easier to delete my old blog and start over from scratch. That was idiot. So now I need to find a way to get it back. The database is there, with all the data, but how do I do to make it work again with the pages and everything?
I tried to reconfigure wp-config.php and entered the name of the database with username and password, and when I when to http://www.site.com/wp-admin or whatever the page the only thing I could see was this strange character at top left of the screen: 
Or else, this message:
Directory has no index file.
Browsing this site or directory without an index file is prohibited.
If you are the site's webmaster, you can remedy this problem by creating a default HTML page with one of the following names:
* index.html
* index.htm
* default.htm
* Default.htm
* home.html
* Home.chtml
NOTE: Filenames are case sensitive, i.e., Home.html is not the same as home.html
Anyone can help me?
