I'm having an issue with warning messages during WP site load and WP-Admin login is prevented by them. It began just after an automatic upgrade of WordPress and appears to be related to the BackupWordPress plugin.

Errors noted below.

I made the additions noted in the WP Forum thread on this topic to wp_config.php:

.....
define( 'HMBKP_MYSQLDUMP_PATH', false );
define( 'HMBKP_ZIP_PATH', false );
.....

But still have the warnings. And it prevents me from accessing the WP Admin Dashboard:
.....
Warning: shell_exec() [function.shell-exec]: Unable to execute 'hash mysqldump 2>&1' in E:\Sites\Single1\battenkillbooks\webroot\index\wp-content\plugins\backupwordpress\hm-backup\hm-backup.php on line 712

Warning: shell_exec() [function.shell-exec]: Unable to execute 'hash zip 2>&1' in E:\Sites\Single1\battenkillbooks\webroot\index\wp-content\plugins\backupwordpress\hm-backup\hm-backup.php on line 739

Warning: Cannot modify header information - headers already sent by (output started at E:\Sites\Single1\battenkillbooks\webroot\index\wp-config.php:1) in E:\Sites\Single1\battenkillbooks\webroot\index\wp-login.php on line 349

.....

Site is live and loads, but has two warnings at the top:

.....
Warning: shell_exec() [function.shell-exec]: Unable to execute 'hash mysqldump 2>&1' in E:\Sites\Single1\battenkillbooks\webroot\index\wp-content\plugins\backupwordpress\hm-backup\hm-backup.php on line 712

.....

Is there a simple way to deactivate BackupWordPress? Or do I have to do a complete manual re-install of WP?
