[Solved] Media Uploader not working

@elia-bizzarri,

Something blocks the native WordPress admin-ajax.php file. The wpDiscuz request returns 403 Forbidden error. Please check your security plugins options and make sure they don't block the WordPress AJAX. This could be also blocked by .htaccess file.

You should disable all security plugins and remember what have you done with your server configuration. If you can't find what could block the WordPress ajax file, please contact to your hosting service support as soon as possible. Once this issue is fixed, all will work fine automatically.

Also, please check this FAQ: https://wpdiscuz.com/community/f-a-q/if-attach-an-image-button-doesnt-work/

Please note all questions related to paid addons should be asked in the gVectors.com forum. Here we only support issues related to the free wpDiscuz plugin.   

Thanks! Where are you going to find the 403 Forbidden error?

Thanks!  Changing the WP Address & Site Address in Settings:General to https: from http:  fixed the problem.
