The error itself shows that adminer.php file was not found on your server, so you need to check for the file adminer.php on your server in adminer directory. It may be removed or renamed, so try to fix it by re-download adminer.php or rename the file (if it is already inside your server in different name) or you don't actually have to rename the file if you rename your link from adminer.php to something (obviously the file name you have in your server inside your adminer directory, it could be latest.php or anything else)

Hey thanks a lot, now i got my adminer working good
