Change DB Prefix
installed change db prefix plugin, can't login to wp admin (4 posts)

    HELP! I did as suggested in Hardening WordPress and changed my database prefix to something other than wp_. I used the recommended official wp plugin "change db prefix", as I don't know enough yet to mess around with my databases manually. BUT once I activated the plugin, I got logged out of my wp-admin and cannot get back in again. And of course the catch-22 is, that I can't change the database back using the plugin unless I'm logged in to wp admin!!
    What do I do please?

    Is it possible that having Bulletproof Security activated somehow requires or calls to the databases by their old name?

    Diana, after you use this plugin to change the database prefix, you have to manually edit your wp-config.php file to change the database prefix there as well.

    Can you try that and let us know if it solves your problem?

    Good luck,

    Hi Fred, thanks for replying. Before I got your answer, I did check that, and found that even though the "change db prefix" plugin documentation says it changes the wp-config.php, it had not. So I changed it manually and it works OK now. But I kept a copy of that changed wp-config.php in case I have to use it again....

    Diana, I'm glad you were able to resolve the problem. A number of people, including myself, have asked the plugin developer to update the plugin so that it edits wp-config.php automatically. Aside from that, the plugin works really well. It does the hard part, which is updating the WordPress database correctly! -Fred
