Lost plugins and sidebars

Hi Guys,

First off, let me apologize if I am posting in the wrong forum but I am a total ‘newbie’ when it comes to word press and unfortunately in my new job I am in charge of development and maintenance.

The issue is that I added in a new image into my theme? I assume (I cannot pin point what I have done wrong) and now, for some reason, but sliders is not showing and also my side bar which had an event. I have tried looking to see where I went wrong, but it all looks fine to me. I cant see any area that may have missing data.

Would anyone be able to help me out? I would seriously appreciate any help I get at this point. Id rather not have to tell my boss I stuffed up big time.. though I may have to…

Cheers!

Oh by the way, my website is http://veracityclinicalresearch.com.au/ but I have it listed for maintenance and I cannot make it live due to the nature of the site.

What can I do?
