Seen the error, access denied, on your blog?

I've noticed that some other bloggers here are getting the same error message as me from their blog posts. When they write their blog posts it comes up as access denied, error. I wrote about this to blogger party some time ago but they didn't reply. I found that if you had more than 2 links in your post it usually comes up as access denied. The post is in the system but it doesn't come up when you try to read it. Thinking it was only me I didnt carry on asking as noone ever answers any of my questions really. But I was just trying to read one of the posts on google adsense sharing and video uploads and how adsense publishers can use their own videos to make money from the google ads. But when I tried to access the post it came up as you are not authorised to access this page, access denied. Anyone else had the same thing? Can you let me know your way round it. Bloggerparty is really good as you get a lot of readers to your posts except there are a few small blogging and technical errors that do come up from time to time. (read my last post)
