[support] D6 - content styling gone?!?!?

[Afan Pasalic]

This is D6 website http://kesarandcosolicitors.co.uk/node/3
As you can see the content of the page lost all html tags (I don’t know how to say it…). when I click on  edit bold, italic, <h> tags are still there but it’s not rendered?!?!?
Input format is Full HTML.

Also, all images on the home page (except slider) disappeared and I when I added <img> on Input formats (/admin/settings/filter) under formatting guidelines.

What’s going on? Is there any chance hosting company did some updates and screwed up the site?
