hi in my website source code i am only getting this code as true var allow_dle_delete_news = true; in my friends website var allow_dle_delete_news = false; when i saw my friends its false what is the use of this and how to change it
No point to change, but you can found this in index.php file (root directory) as var allow_dle_delete_news = true; line..
This is only whether you want your users to be able to delete articles or not. If it is true, then anyone can delete his own articles. If it is false, only admin and mods can delete articles. Hope this helps.
