Your site was working great last night. Everything was great and you've done nothing. This morning, your site is down and/or you get a note that says you must run WordPress install.php again.
With the recent viral worm hitting the net, I'm hearing from some people that their site host is now taking new security measures, often requiring a new password. This is great but it has some complications.
Access the control panel of your site and you might be met with a new password required login screen.
1. The password must now include a non-word character. This means $%&*()#@! type words so the password would be something like ab4cd#f.
2. You may have more than one password. You have the password for your server site and another for your database. Both of these may need to be changed. If you cannot easily change you database password, contact your host
3. You may need to change the
wp-config.php in your WordPress root directory to the new password.
4. If you use FTP or other site access software, make sure you change the passwords there, too.
5. If you do the SMART THING and keep a record in writing of all your passwords, make sure you also update those.
As soon as you get back online, test your site thoroughly to make sure all parts and pieces are working and backup your entire site.
