Recently I have received a couple of emails like this one, from readers of my blog who subscribe to my blog in RSS/email newsletter format:
"I have been receiving your email from your blog for many months.
"Lately there have been huge white gaps w/ the msg 'blocked plug-in'.
I have a 'Mac'.
"If u have made changes to your website transmissions, is it compatible w/ a Mac?
"I have checked w/ my server (telus), Apple, and Norton antivirus; they all say that it must be a problem w/ the website.
"Can u help?"
My blog is on a dedicated server at DreamHost. They suggested I ask about this at WordPress Support.
All my plug ins are the latest versions.
