Try to set a comment and get the error.

You have some comments already, so did this only start happening recently? Perhaps shortly after you upgraded to WordPress 2.8 or installed a new plugin? If so, try deactivating all plugins to see if this resolves the problem.

Thanks for answer me.

The last monday I install the plugin “WordTwit 2.0.7” ’cause was a great solution for tiny url with my own domain. But the plugin change the whole url’s in the site.

That is a problem for the crawlers so I uninstall it. Yesterday a visitor alert me about the problem. The last sunday some of my visitors left commments but now they are getting that message, so the problem begun when uninstall the plugin.

Any solution or I need to reinstall everything ??

Hi. I’m still on version 2.7.1 although I’ve had this problem when I activated a new theme. I switched to another theme and users were able to post comments again. For what it’s worth I just thought I’d mention it.

In my case, it’s the WP Captcha Free plugin that WP 2.8.5 doesn’t seem to like. :\

The administrator should be able to create only one post per day.
How can i acheive this ?
please help!!!

Junih, I tried to leave a comment, and I didn’t get an error.

Had this same problem until disabling the WP Captcha Free plugin with WordPress 2.9

WP Captcha Free was killing my comments too!
