Hey folks,

wpmudev support is enabled.

***Instead of doing it yourself, can you review and then let me know what the solution is so we can apply direct on this one?

So, far this is added in Custom CSS plugin (at the bottom):

div.su-spoiler-title {
background-color: #05509f !important;
}

span.su-spoiler-icon {
color: #ffffff !important;
}

.su-spoiler-style-fancy.su-spoiler-closed > .su-spoiler-title {
color: #ffffff; font-weight: normal; font-size: medium; !important;
}
