A site I help with http://www.newsatden.co.uk has sometimes started to through up 403 errors, a directory listing (the Devs obviously never disabled this) or the RSS for the page instead of rendering the page correctly. The strange this is that if you refresh the browser the page often loads correctly.
My initial thought was that this would be Malware – but then I would expect it to redirect me somewhere else – but a refresh often brings in the correct page.
A scan has brought up nothing obvious other then 5 inserts into some comments which have been moved to quarantine so I don’t think my issues relate to this.
Is this likely to be Malware that isn’t being found by GOTMLS or some other issue?
