[#11342]

Hello,

Since I updated to version 7.6.47, my readers can no longer post comments; they receive a "nonce is invalid" error. i have cloudflare + APO cloudflare

I don't have this problem when I bypass Cloudflare by hardcoding my server's IP address in the hosts file.

The only solution I found was to roll back to version 7.6.46, and that resolved the issue temporarly. Readers were complaining about no longer being able to comment on articles.

I'm waiting for a solution in a future plugin update. The problem is the same after cleaning all cache. Only rollback in 7.6.46 is ok for the moment.

Thanks

for precision:

Since updating to wpDiscuz 7.6.47 (March 11, 2026), visitors receive a "nonce is invalid" error when submitting comments. Reverting to the previous version immediately resolves the issue. The site is hosted behind Cloudflare, but the behavior is directly related to the 7.6.47 update. Please investigate whether there is a regression related to nonce validation/AJAX calls. Maybe
