No shortcodes working at all

Hey,

I have just set up a www.remarpro.com site and all working fine except I can’t get any shortcodes to work. I’ve tried looking at other forum posts but couldn’t find anything to fix the problem so really looking for some help.

Some details:
1. I’m using the standard twelve thirteen theme (no changes)
2. WordPress version 3.6.1
3. I deactivated and uninstalled all of the plugins

Here is an example:

I was original using two plugins (Custom Facebook Feed Pro and Google Simple Maps) which used shortcodes but would not work. I uninstalled these and tried the basic WordPress shortcode for Youtube to see if it would work but as you can see, no job.

Could anyone assist me in making shortcodes work? I am lost. I’m not that technical so apologies if this has already been answered or I’m doing something dumb!

Thank you in advance.
