Every time I try to search for comments it takes a while and it ends up with that error message:

Fatal error: Uncaught mysqli_sql_exception: Query execution was interrupted (max_statement_time exceeded) in /var/www/imcdb/yourcomments.php:193 Stack trace: #0 /var/www/imcdb/yourcomments.php(193): mysqli->query(' SELECT SQL_CAL...') #1 {main} thrown in /var/www/imcdb/yourcomments.php on line 193
