Yes, have had the same on a couple of occasions, not sure how that happens.
Another interesting little quirk happened today, I lost the footer on my home page, with the page finishing at the referrals list, it appears that a particular referer URL caused the problem, but I can't think why.
Normal page
Attachment 67176
With bad URL
Attachment 67173
This was the referral URL, have added the underscore at the beginning to prevent it from parsing. _http://gardenworld.proboards103.com/index.cgi?board=photos&action=display&thread=11688 79705&page=6
Any ideas why this causes the footer not to load?
