I don't know which version of WordPress my site is running off of, it was out in 2012. Basically, I uploaded the files to my new host and changed the wp-config file to point to the new database. After, I uploaded the backup database file to the new database and had to manually change the domain name in some tables and the home directory. The site is still not loading. It comes up as a blank page. I check that the domain is working just fine and the tables in the database have been activated. What am I doing wrong?
