[Solved] no post button?

When I tried to post a comment, it gives me the error message that I have an invalid capta code. I have capta turned off. This isn't working yet.

Please make sure you don't have other CAPTCHA plugins. This error comes from other CAPTCHA plugins, you should disable other CAPTCHA plugins for comment form.

I think I figured it out. Wordpress logged me out and I didn't know it. Once I logged back in, the problem went away.
