Title: Problem with WPBruiser Last modified: August 9, 2018 --- # Problem with WPBruiser * [tmwnn](https://wordpress.org/support/users/tmwnn/) * (@tmwnn) * [7 years, 9 months ago](https://wordpress.org/support/topic/problem-with-wpbruiser/) * Hi, * We’ve been using WPBruiser (from [@mihche](https://wordpress.org/support/users/mihche/)) for a long time without any trouble for our users. * A couple days ago, I installed and activated WP-Discuz on our busy site (along with your commercial media upload add-on). There are a lot of regular commenters on the site (e.g. there were 277 comments posted yesterday). Many of the regular commenters are repeat “guests” – meaning they are not logged in to the site, having just filled in a name on the comment form and keeping that identity via the wp cookie. * I have disabled the WP-Discuz invisible spam protection by blanking out the Invisible Spam Protection field. * A few commenters are having their “reply” comments bounced by WPBruiser with either “Invalid Token” or “Browser Info Invalid” errors. These must be “guests” as I have the WPBruiser “Disable Protection for logged in users” setting checked. As far as I can tell, these same users are able to create comments successfully using the main comment form to create top-level comments; they are only having issues creating replies to existing comments. * I tried testing by visiting the site from a non-logged-in browser and reply commenting as a guest, but I had no issue, and many of the guest commenters are also not having an issue, so it is not easily reproducible, though for the users who are having the problem, it happens repeatably. None of them so far are tech-savvy enough to give me more information. * I have cleared all caches and told the users to clear their browser caches (and gave them a link to a page that explains how to do so in all browsers), but the problem remains for some. * Here’s a link to the test post on which we announced using WP-Discuz and invited users to post test comments below: [https://www.theburningplatform.com/2018/08/08/new-tbp-comments-plumbing/](https://www.theburningplatform.com/2018/08/08/new-tbp-comments-plumbing/) * WP-Discuz v. 5.1.5 WPBruiser v. 3.1.19 WP 4.9.8 PHP 7.2 Viewing 4 replies - 1 through 4 (of 4 total) * Thread Starter [tmwnn](https://wordpress.org/support/users/tmwnn/) * (@tmwnn) * [7 years, 9 months ago](https://wordpress.org/support/topic/problem-with-wpbruiser/#post-10578438) * Testing, 1,2,3… * [@gvectorssupport](https://wordpress.org/support/users/gvectorssupport/) are you around here somewhere? * Thread Starter [tmwnn](https://wordpress.org/support/users/tmwnn/) * (@tmwnn) * [7 years, 9 months ago](https://wordpress.org/support/topic/problem-with-wpbruiser/#post-10578817) * I see that you just posted a test comment on the site. For user’s convenience, I have turned off WPBruiser comment protection temporarily so you will not have seen whatever the problem is. I will turn it back on and clear caches. Please wait a few minutes and try again. * EDIT: Ok, WPBruiser comment protection is turned back on. * Plugin Support [gVectors Support](https://wordpress.org/support/users/gvectorssupport/) * (@gvectorssupport) * [7 years, 9 months ago](https://wordpress.org/support/topic/problem-with-wpbruiser/#post-10578937) * Hi [@tmwnn](https://wordpress.org/support/users/tmwnn/), * I’m sorry, but we don’t find this issue. Also, we don’t find it on our test websites. We’ll keep testing and let you know if we find such an issue. * But probably this is your website specific issue. - This reply was modified 7 years, 9 months ago by [gVectors Support](https://wordpress.org/support/users/gvectorssupport/). * Thread Starter [tmwnn](https://wordpress.org/support/users/tmwnn/) * (@tmwnn) * [7 years, 9 months ago](https://wordpress.org/support/topic/problem-with-wpbruiser/#post-10578987) * Hi [@gvectorssupport](https://wordpress.org/support/users/gvectorssupport/), * As mentioned in my original post, I also can’t reproduce it. But it consistently happens to some people on our site. * Since the people who are affected can post top-level comments, but not replies and since the problem is related specifically to WPBruiser spam protection and gives either an “Invalid Token” or “Browser Info Invalid” error, can you tell me what the differences are between the main comment form and the reply comment form that could be related to those errors? What token is WPBruiser looking for? How is that token injected into the POST request when a comment or reply comment is sent? * I am a WP plugin developer. Tell me where to look in your plugin and I will audit it and see if I can find anything useful to add.
