I've installed the plugin "WP Security Scan" on a fresh install of Wordpress 2.6 running on a Apache server at hostgator & the plugin says this about my table prefix. Your table prefix should not be wp_. Click here to change it. Change your database table prefix to mitigate zero-day SQL Injection attacks. I going to be installing WP Super Cache or Hyper Cache to keep my server from crashing if I get a lot of traffic. If I change wp_. to say ab_. will it affect the cache plugings and the SQL database & will I have any future problems with the database.
