Bug, where?!

Somebody mentioned that there is a bug on my site.
They couldn’t tell me how it happened, but they said the site ‘restarted’ and it happened when they did something related to the services section.
I’ve previewed my own site LOTS of times and have enevr seen this happen,s o if someone happens to be able to recreate this bug and tell me what you did to make it happen i will try to fix it.
EDIT:
Hehe, forgot the link,
