I have been receiving this message for 4 days now. Initially it occurred while editing. Sometimes it was sporadic. Now it is constant.
I use Firefox but had a similar message on Safari.
I have cleared cookies and caches, removed Adblock and changed that setting in Users (http??? whatever - saw the suggestion on the forum)
But now I can't even see my blog. I am well and truly furious and upset.
The blog I need help with is anaturallifeforjetandwalle.wordpress.com.
