Unable to post an OP in some forums, getting "403 Forbidden" error

I've tried and failed to post an OP in GD more than a dozen times over the last few hours.

I tried to post in the Computer Support forum, same content as attempted GD post, and got the same error.

Tried a test post here in Community support, different content than failed GD post, and it worked.

1. This can sometimes happen if there are special characters in the text you're trying to paste

Try pasting a bit at a time and using the Preview button as you go -- hopefully then when you get the 403 you can identify which part of the content is causing the problem.

I'm doing that as we speak, in the Google AI/Robert Redford thread.

I've narrowed the problem down to the paragraph containing the Google search string that I had used.

3. It looks like the capitalized version of *or*, enclosed in quote marks (double or single) is the problem.

I tried including that term in this post and got the same error.

A weird aspect is that my GD post let me use *Or* (in double quotes), but not *OR*(in double quotes). When experimenting with *OR*, or *Or*, (between double quotes, not asterisks) in this post, I get the 403 error for both versions.

I just tested it and got the same result you did. I know that we have some security measures in place to prevent certain text strings from being submitted to the database because they could potentially be used in an attack. Personally I don't know enough about it to know what is forbidden and what isn't, but I guess you found one that is disallowed... hopefully you can just work around it.

8. Yes. And I fixed it and posted it, but that wasn't the problem.

It was a forward slash on a link and another link that was wrong. (I got the whole text from someone else.)

But anyway, it's up now.

I knew where we were going with the name "Null", but never would have thought that "McKenzie" would present a problem.
