No this is never going to work at all. When you are hacked you are in deep trouble and the only thing you can do is following all (!!!!) steps as outlined here: http://forum.joomla.org/viewtopic.php?f=621&t=582854

You cannot leave a single step! Pls follow up or you will be hacked again!

ok i found the idiot who was i think sending from this site and deleted him in database - have uploaded my backup and the site sort of working apart from the google map page - i now want to upgrade from 1.6 to 2.5, i have installed Admin Tools Core 2.2.a3 but there seems to be no way to update joomla ( THOUGH THERE IS A BIG BUTTON SAYING reinstall 3.2.0-ALPHA and i am afraid to do so)- so how can i do it manually? and would be nice to get the googlemap working again...

Do NOT i repeat NOT install version 3.2.0 on a live site ! That is not a stable version!

Go to components/Joomla update / Options and set the update preferences to Short term Release and save. Reload and you will see Joomla 3.1.5 appearing

did the upgarde go successfully or did it fail?
did you ever have a working 2.5 site?

Go to components/Joomla update / Options and set the update preferences to Short term Release and save. Reload and you will see Joomla 3.1.5 appearing

you should look for the 2.5 version not the 3.x
failing that you should start from your back up and after removing the "naughty" user start the methodical update process.

Hi in components there is no joomla update - there seems to be no way to update so i have this code to update the database to enable the updates hopefully but it does not work

UPDATE #_menu SET component_id =
(SELECT extension_id FROM #_extensions WHERE name = "com_joomlaupdate")
WHERE title = "com_joomlaupdate"

As I get this answer

SQL query:
UPDATE SET component_id = (
SELECT extension_id
FROM WHERE title = "com_joomlaupdate"
MySQL said:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET component_id =
(SELECT extension_id FROM WHERE title = "com_joomlaupdate"' at line 1

any ideas - as i really need to upgrade
thanks

have sorted out the script above - the # is the database prefix - so the call works but i can still not update the joomla - there are no links anywhere in admin to do so?
How can i work around this?
thanks
