I had removed the Report link under the messages, but forgot to remove the Report link in Private Conversations. I don't want to use the Report system at all.
Using phpmyadmin, I deleted the single row in xf_report and xf_report_comment, I assumed that would clear the Reports notice but it did not. My question is, what table holds the information for that Reports notice? I would like to use phpmyadmin to remove the data so the alert notice is removed.
