Hi,

I have a 1.5.26 joomla site which has been attacked and K2 users has been compromised and used to help a porn download site gain my users... As a result I am now blocked by Google and I have a lovely skull and crossbones and a warning to leave appear as you enter my site.

I tried your download to update the site and this bought the whole site down with a fatal error as follows:

Fatal error: Class 'K2Model' not found in MySite....

How can I upgrade my vulnerable K2 2.4.1 to the newest version without losing my site again?

Help - please.

make (database) backup of your content and settings, after that do clean install of joomla and k2
