I used to use video pop-up feature a lot. Using “mfp_iframe_popup” extra class.
It worked like a charm, but since I upgraded the theme, it doesn’t work.

Should I use another class name? Could you please help me?
THANKS!

my site is here, you can see the video button in each tab: http://sitedemo.proreact.dk/ibg-moduler/

How can I manually set the font type of tabs menu items?

I am using Oswald font a lot in the site and i want to use it also for the menu in the tabs without affecting my regular body text (which is source sans pro).

Thanks a lot! This would be a lifesaver!

The JS error you get is in this file:
plugins/forms-for-campaign-monitor/js/lightbox.js?ver=1.0.0

Seems like the mfp_iframe_popup is conflicting with the lightbox plugin you are using. did you have it beforehand as well?

.resp-vtabs ul.resp-tabs-list {
    font-family: Oswald;
}

About the video problem, i haven’t installed lightbox plugin, was it part of the theme? Since i dont see it in my plugin list on WordPress. Is there any way you could help me solve it?

About the custom font thing:
.resp-vtabs ul.resp-tabs-list {
font-family: Oswald;
}

Where should i put it?

Thanks!!

Add the custom CSS to your Theme options->Custom CSS!

As you can see the lightbox that errors is here:

http://sitedemo.proreact.dk/wp-content/plugins/forms-for-campaign-monitor/js/lightbox.js?ver=1.0.0

So check by disabling this plugin.

Could you please help me to find that plugin and disable it?
I can’t see it in the list of installed plugins…

Would it be easier if i give you access to the site?

This should be the name of your plugin.

thanks again!
