WP Database Name

I tried to change the prefix using the tool provided but got a fatal error

What is the exact error?

Here is the error:

Fatal error: Call to undefined method mysqli_result::fetch_all() in /home4/h612003/public_html/momandpoptoday.com/wp-content/plugins/all-in-one-wp-security-and-firewall/admin/wp-security-database-menu.php on line 534

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.

Ok, thanks!

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.

I just wanted to let you know I was able to change the DB prefix following the install of the last update. Thannks, Bill

Glad to hear that.
