Upgrade has disabled the admin of my blog
Blog still loads, but admin gives this error:
The specified CGI application misbehaved by not returning a complete set of HTTP headers.
The upgrade.php file gives this error:
WordPress database error Unknown system variable 'NAMES' for query SET NAMES 'utf8' made by require, require_once, require_once, require_wp_db, require_once WordPress database error You have an error in your SQL syntax.
MySQL version is Client API version 5.0.22
What's the problem?
