Conflict with jetpack comments

Hello,

When I try sending a comment in my website posts or articles, I have this error message : ‘ Invalid request signature or no blog id supplied ’.

While trying to resolve it, I found in jetpack support that some plugins could be in conflict. So I disbaled all my plugins and the one messing out is wordpress video gallery.

In jetpack support they say that the conflicting code is:

/*  Fix YouTube iframe overlay and z-index issues

https://maxmorgandesign.com/fix_youtube_iframe_overlay_and_z_index_issues/

------------------------------------------------------------------------------- /*
    jQuery("iframe").each(function(){
        var ifr_source = jQuery(this).attr('src');
        var wmode = "wmode=transparent";
        if(ifr_source.indexOf('?') != -1) {
            var getQString = ifr_source.split('?');
            var oldString = getQString[1];
            var newString = getQString[0];
            jQuery(this).attr('src',newString+'?'+wmode+'&'+oldString);
        }
        else jQuery(this).attr('src',ifr_source+'?'+wmode);
    });

So I looked at all contus video gallery files but I haven’t find it.

Does someone know how to fix this issue?

Thanx a lot
