Here is the trick for closing wordpress post and pages comments at once , including old ones:
For closing all comments in all post and all pages there is a easy way :
Go to CPANEL > phpmy admin > execute following code in your database(in good one !)
UPDATE wp_posts SET comment_status = ‘closed’, ping_status = ‘closed’ WHERE comment_status = ‘open’;
if you don’t know database name :
cpanel > file manager > public_html > navigate until..your site > and right click on wp-config.php > wiev !
you will see the data base name inside of this file !
SEE FOLLOWING IMAGE FOR SQL EXECUTION PROCESS !
IF ANY ERROR MESSAGE LIKE :
#1054 – Unknown column ‘‘open’’ in ‘where clause’
Paste your code first in notepad and verify ” ‘ “ sign !!!
