server side bug Answered
Recently I've been posting the odd code sample from Arduino sketches into answers.
I open the source view option of the rich editor, and paste the HTML copy from Arduino 1.xx
That's code with the pre tags set start and end.
I close the source view, and my rich edit preview is fine.
I post the message, and all hell breaks loose - I see the "Instructables is down " message in the middle of the postings, and all the text becomes centred.
This is FF18, but the error seems to come from Instructables - or where would your "Instructables is down" come from
