 * When I check the Data Base Security section of the features, it tells me that
   my DB name begins with the wp_ prefix. Yet when I look at the wp-config.php file,
   the DB Name does not begin with wp_
 * Before I looked at the config file, I tried to change the prefix using the tool
   provided but got a fatal error.
 * Any ideas
 * thanks,

 * Ok thanks.
    This confirms my suspicion – basically your server does not have 
   a particular MySQL driver which is required to run the “mysqli_result::fetch_all()”
   method.
 * We have a fix which will be available in the next release where we have modified
   our code to use a different method so that we can prevent errors like the one
   you are seeing from occurring.

 * Hi,
    I received the same error but under a different circumstance. I have a subdomain
   on my website that has its own WP install and database with the database prefix
   changed using your plugin. I duplicated the subdomain (duplicator plugin) that
   involves creating a separate database for the new subdomain. When I went to change
   the database prefix on the new subdomain (because the subdomain was duplicated
   it would be for the second time) I received the error.
 * Can a database prefix be changed more then once using your plugin?
 * Thank you for your time.

 * You can install the security plugin in each of your WordPress install and change
   the database prefix of that install. I am not sure about that duplicator plugin
   you are talking about though.

 * Hi,
 * Thank you for your response.
 * Your v3.7.2 update allowed me to change the database prefix that had previously
   given me the error message.
