Images have disappeared from live site

Hi,
Some random images have disappeared from my live site: http://www.lifeterapias.com.br
There are in the media library, they figure on the page when I am in Edit mode, but they can’t be seen. Some pieces of text have also disappeared.

I have alerted my host also.

Here’s what I was doing:

1) I had a fatal error: Call to undefined function array_replace_recursive() in /home/lifet854/public_html/wp-content/plugins/lead-capturing-call-to-actions-by-vcita/core/settings.php on line 168 – after installing this plugin. I could no longer access the admin panel, but the site was working perfectly live.
2) Via FTP, I removed the lead-capturing-call-to-actions-by-vcita/ plugin
3) Access to the site was normal again, so I update a few plugins (can’t remember which ones though there was Backupdaddy)
4) I modified one page http://lifeterapias.com.br/terapia-vidas-passadas/como-funciona/, basically adding one element. When I checked the live version, some images had disappeared. And it happened on almost every page, randomly.
5) Some texts have also disappeared, for instance on the page: http://lifeterapias.com.br/terapia-vidas-passadas/. A text on the school image, the testimonials plugin and the animated numbers plugin. Once again, they are all present on the page when I edit it from the admin panel.

What can I do ?
Thank you.
Steve
