It may be a long shot, but try it from another computer, maybe its your virus protection or firewall blocking it.

I was getting a forbidden error in my google chrome browser, it would not open any webpage. I found out my firewall was blocking the pages from opening.

I didn't know we were allowed to link to our own sites. Is this new ?

It works for me too.

Did you just install those ad units to your web pages? If so then that's normal. I have seen that for code that has just been placed on a web page. It's a temporary error that lasts a few minutes to a few hours. Google's systems haven't updated the new ad unit and so it temporarily does not show ads for those web pages because it thinks they do not exist in it's systems. Hence the 403 error code:

The server understood the request, but is refusing to fulfill it.

Thanks for the replies..

snickles121: Tried that, same results. As mentioned, if i merely copy the source of the page and paste into an .html file it will work. It appears to have something to do with the url

martinibuster: Nope, they've been there for years. (No idea when this started happening though.

Lame_Wolf: As you can imagine there's no other way for me to demonstrate what's happening. I neither need the traffic, nor the promotion on WebmasterWorld. I've been a member for 8 years, I figure I know when something is inappropriate or not. That been said, sorry if it is!

URL drops are being allowed in specific cases I believe.

Very strange ads I'm seeing in the UK!
