I`ve uploaded a little site already a few months ago. Everything "seemed" more or less ok, but then one day an WARNING message (see attachment) started to occure from time to time. If you refresh the browser the message mostly disappears. As I am not a real coder - I am not really aware of how or where I can solce this problem.
You can find the live site here: http://alexfischer.org/
Any idea? I am sure its just a minor problem! Thanks in advance!
