I acnnot post anew to my blog because my Update (Post) button has “disappeared” again–you may recall that this problem occurs every month or so; usually nobody understands what I mean, and/or they see no problem.
Yes I have cleared history, cookies, etc. shut down pc, etc, etc.
This “problem” usually passes in a day or so, ‘cept weekends…
I don’t know how to help you other than to suggest that if you don’t have a browser issue then you probably have a connectivity issue. How are you connecting to the internet and to WordPress.com? The way you connect to the internet (mobile, satellite, DSL, dial-up) and to your blog, and how many proxy server jumps etc. it takes to connect can cause problems. There maybe be problems with your ISP and/or with the proxy servers. Have you checked with your ISP to see if there are any known issues?
