I too had this issue and found countless other posts dated many years ago with no solution. I am using bbpress v2.5.4 and buddypress v2.1.1 on WordPress v4.1. I “resolved” this by editing my functions.php file within the bbpress plugin directory and replacing any character values with a blank. Good enough for me. This “solution” IS NOT RECOMMENDED as any update to bbpress is more than likely to overwrite it. Unless you don’t mind going back in and remembering to re-hack it after each update. No doubt it can be done better. The client just requested I get rid of the code values. Without further to do…
GoTo: yoursite\wp-content\plugins\bbpress\includes\common\functions.php
Between Lines 1090 and 1091 Add:
$search_bbpress_titles = array("&# 039;", "&am p;", "R 11;", "&qu ot;"); // ' & - "
$topic_title = str_replace($search_bbpress_titles, '', $topic_title);
Then add the same two lines further down between Lines 1233 and 1234.
NOTE: You will have to remove the spaces from the $search_bbpress_titles array line as I was unable to post without it parsing that line. Don’t know the coding on this form to post properly. Email me if you need the code.
Looking forward to any other helpful input. No need to remind me how better you are at coding. 🙂
Had same issue. Disabled WP-Mail-SMTP and worked for me.
