 * Is that from a fresh copy of WP 2.8 install files?

 * yes, sometimes a fresh copy can also have a bug. check this:

 * I am not sure about this error, but this is the code:
 * `$data = $this->_weak_escape( $data );`
 * so try removing space between ( and $
 * This should solve the issue

 * OK…So I installed an old version of wordpress in another area.
 * I NEED to get this working.
 * When I enter my database info from the OLD config file I get…
 * **Error establishing a database connection**
 * Can someone help me get this going?

 * Looks like you mis-typed something into your wp-config.php file. There’s also
   no guarantee that a WP 2.8 database will work effectively with an older version
   of WP.

 * I would bet your old database (old install) was using a custom theme that is 
   not in your new source code? Or, you didn’t disable all the plugins before you
   upgraded? Try disabling all plugins in your old database via phpMyAdmin…see the
   following video…

 * THANK YOU!!!
 * That solved it!
 * I really wish wordpress would install a small warning on the auto-upgrade that
   said “besure to turn off all plug-ins before auto-upgrading”
 * Thank you again!
