Hi I was just having the same problem with one website only - my 2nd own site that I had just published to host. I had published a first one a few days prior and that worked fine.
Performing that 8 8 8 8 reset as per devgoat's reply (01-22-12, 01:09 AM) did the trick.
I don't really understand what I've done there. That is to say that all the other sites in the world were working ok with the old settings so I am sorely vexed as to why only my new site needed that..
Any clues as to what I have technically done here?
Thank you.
