Support Forum

My template is so complex, there are hundreds of php files. No one is called bootstrap.js or something. 

i can't start a forum without image upload. 

On the support forum of my template, some people ask the question too and someone fixe the problem with this code in his function.php : 

add_action('wp_enqueue_scripts', 'deregister_pl_bootstrap', 100);
function deregister_pl_bootstrap() {
    if(sp_is_forumpage()) {
        wp_dequeue_script('pagelines-bootstrap-all');
    }
}

But it's not working for me. 

Can i give you an admin access to my site and/or ftp access to all my files, so you can look. i'm not in a hurry, you can take your time!

I tried this solution too, but i don't have action.site.php.

the solution you gave by the past are for Pagelines Framework, it's an old theme. I use Pagelines DMS2, wich is a totaly new theme. That's probably why all the solution doesn't work. 

in the new theme, i found 7 php files that have the word "bootstrap" in it. and also xml, js, less and css files. 

I will try to look and find which php files to modify and try the old solution, maybee...
