Bug Users Not Allowed to Like Comments After Update to 7.6.48

After updating our independently hosted WP site to wpDiscuz version 7.6.48, none of our users, either registered users or guests, with any level of permissions, including admin, were able to add likes to any comments.  The message (red dialog) was “you are not allowed to vote for this comment."

Rolling back to 7.6.47 fixed the problem for all registered users.  We had previously noticed that guests were unable to like comments after a major WordPress update, possibly in 2025 - this was despite the setting allowing guests to rate comments being turned on.  We chose not to submit a report on this feature breakage for guests until now, since it was more of a WP core issue at that time.

Please note that we do not have JetPack installed, but we did add your suggested code snippet to disregard nonces for guests, since some users and especially guests seemed to experience the red nonce warnings.  With 7.6.48, the red message dialog was the same for both registered users and guests, that they were not allowed to vote.

Thank you in advance for looking at this.
