WordPress MU

I enabled DB Cache to test it and now all I see are blank pages for all of my blogs. I tried going into the database with phpMyAdmin and clearing the active plugins, but that didn't help.

Any ideas???

blank pages means an error. Check your error logs.

Go into wp-config.php and add a line near the top with:

define( 'WP_DEBUG', 'yes' );

Reload your page and the error that is causing your site to stop working should be displayed at the very bottom of the page.

This is my error log:

Fatal Error
If your blog does not display, please contact the owner of this site.

If you are the owner of this site please check that MySQL is running properly and all tables are error free.

Database Tables Missing.
Database tables are missing. This means that MySQL is either not running, WPMU was not installed properly, or someone deleted . You really should look at your database now.

What do I do now?
Read the bug report page. Some of the guidelines there may help you figure out what went wrong.
If you're still stuck with this message, then check that your database contains the following tables:

*
* wp_users
* wp_usermeta
*
*
*

If you suspect a problem please report it to the support forums but you must include the information asked for in the WPMU bug reporting guidelines!

Which db plugin are you using?
