Thank you for your reply Robin, however Genesis Extend is installed.

I have pinpointed the problem.
This section in the BBPress.css is breaking my themes:

@media screen and (max-device-width: 480px), screen and (-webkit-min-device-pixel-ratio: 2) {
-webkit-text-size-adjust: none; {
}

@media only screen and (max-width: 480px) {
#bbpress-forums div.bbp-topic-tags {
clear: left;
float: left;
}
div.bbp-search-form input,
div.bbp-search-form button {
font-size: 11px;
padding: 2px;
}
li.bbp-forum-info,
li.bbp-topic-title {
width: 45%;
}
li.bbp-forum-topic-count,
li.bbp-forum-reply-count,
li.bbp-topic-voice-count,
li.bbp-topic-reply-count {
width: 15%;
}

float: left;
}

clear: left;
float: left;
}

When I remove:

@media screen and (max-device-width: 480px), screen and (-webkit-min-device-pixel-ratio: 2) {
-webkit-text-size-adjust: none; {
}

@media only screen and (max-width: 480px) {

@media only screen and (max-width: 240px) {

@media only screen and (max-width: 240px) {

The site looks OK again.
Anyone know if it’s safe to remove those??
