Hi some one hacked my joomla site,
I am not able to access to "administrator/index.php?option=com_config", it is giving 404 error. The hacker is "hacked by s13doeL", he added "joomla.class.php and index.old.php" in all over the web files.
I think there is only one solution, reistall everything. Could someone help to migrate from 1.5.18 to 1.5.20. I do not want to change to 2.5 because that template is not supported to 2.5.
Is it just enough copy all database and then link to it? Does it copy all old articles? or do I have to copy ann manualy?
