I recently saw some bogus posts on my wordpress site, so remained calm and visited http://codex.wordpress.org/FAQ_My_site_was_hacked. After changing my password, I still saw malicious activity so I changed the access keys according to the above site (using WP's automatic key generator).
Once I changed the keys, overwriting wp-config, my wordpress site became unusable, and I get the message:
Parse error: syntax error, unexpected $end in /home/content/10/9558610/html/wp-config.php on line 1
Is there any way for me to get the site back? What could I have done by changing the access keys that would affect things in this way?
