getting into the site or posting?

I have been having a lot of trouble lately. It keeps saying that it is not a safe site and refuses to let me open it over and over.

When I finally do pry it open it won't let me post until I do that over and over, then finally get a screen to weed out robots by making me put in a string of numbers. Even then sometimes it fails.

Is it my security or is this board wonky today. I saw where CindyH's post showed up twice and thought it might be the board.
