 * Dear wpDiscuz Support Team,
 * After i update wordpress to 6.7 and above, i have faced several bugs from wpdiscuz.
   I am writing to report a fatal error I encountered on my WordPress website after
   a recent update or installation of the wpDiscuz plugin. I am receiving the following
   error:
