Hi All,
I was recently alerted to a problem which has occurred at least twice on my site's wpDiscuz comment system since I set it up a few months ago.
The problem is this: a user posts a comment. Then a different user posts a comment - but that comment shows up as being from the first user!
Looking at the second comment's details, it has the first user's name and email, but a different IP. I don't think these are hackers or anything weird - it's got to be a bug somewhere.
Has anyone else experienced this? Any ideas? Obviously my users are get annoyed - especially the ones whos names are being falsely attached to posts!

Hi @e-schlange,
Could you please deactivate the wpDiscuz plugin and check again? Please let us know how it works without the wpDiscuz plugin.

The problem is that it's a rare issue--I don't know how to replicate it. I turned off the plugin, which made comments look kind of wacky on the site for a while... but I ended up turning it back on.
One user told me when they went to comment, another user's name and email address was pre-populated into the comment form. So this is what's happening.
I have a theory: that it's my CPanel OPCache doing it. That sometimes, a user submits a comment, and the site then caches their particular view of the page.
I see the OPCache settings include a "cookie bypass" option. It is described as "List of string to match in the Request cookies that will trigger a cache bypass. This is important to ensure that logged in users' pages are not being cached and shown to other visitors. The default setting should work with most Wordpress sites, but may need to be updated for certain plugins, or if using a CMS other than Wordpress."
This seems like it would do the trick, except it appears the two cookie values used by your system have a random string attached to the end, so I can't just put in a cookie key. Is that true?
I can also have the cache bypass certain URLs... but I don't think there's a way for that to work.
Any other insights you can provide would be great. Thanks!

One correction: the caching I'm configuring is NGINX caching, not the OPCache.
