How can disable via software/db memcached server?

After a simple restart of my memcached server in my account, i cannot connect anymore always this error:

Warning: Memcache::connect(): Can't connect to 127.0.0.1:20048, Connection refused (111) in /home/cupido/public_html/loveschool.it/inc/classes/BxDolCacheMemcache.php on line 23

Warning: Cannot modify header information - headers already sent by (output started at /home/cupido/public_html/loveschool.it/inc/classes/BxDolCacheMemcache.php:23) in /home/cupido/public_html/loveschool.it/inc/admin_design.inc.php on line 51

I check all, hostname, port, delete all cache and restart but nothing.

I cannot enter in the admin panel to disable memcache in the meanwhile, how can do this via code or databases?

Thanks for your answer...

You can edit them from the database with phpMyAdmin or similar:

* sys_db_cache_engine: DB cache engine [File,Memcache,APC,XCache]

* sys_pb_cache_engine: Page blocks cache engine [File,Memcache,APC,XCache]

* sys_mm_cache_engine: Member menu cache engine [File,Memcache,APC,XCache]

* sys_template_cache_engine: Template cache engine [FileHtml,Memcache,APC,XCache]

Switch any set to "Memcache" back to "File" or "FileHtml" and save. Then empty the /cache directory (except for any .htaccess files).

Ok thanks Nathan,
i reset all parameters and resolved this issue, now i can access to admin panel and make another settings.

Thanks a lot for your answer!
