Facbook links hijacked in MODx 1.0.5 for one of my sites

Hi there

Once of the sites I run has been hijacked twice, and although a reinstall eliminated the problems it has come back. Does anyone have a similar experience of this and any measures to eliminate? I’m running the site on 1.0.5 running on Apache/2.2.14 (Ubuntu)

When links are added to Facebook they show up with Vi@gra in the title link and description meta but it appears the link still works okay.

Thanks

Could you tell us more about your hosting environment and what addons you have on the site?

Hi AMDBuilder and thanks for your reply.

I am running the site on a Linode VPS with Ubuntu 2.6 Paravirt with Apache/2.2.14

The addons I am using include

ajaxSearch (build supplied with 1.0.5)
getField
phpThumb
DittoCal for the calendar entires that are parsed in from JSON

I am also pulling in RSS feeds from Flickr using MagpieRSS

Thanks, Jim
