Here are a few tips which should help you get your galleries working as expected:
(1) Load the 'juicebox.js' file only once per web page (not once per gallery).
(2) Unless your galleries are nested within parent containers which have been given dimensions via CSS, set gallery dimensions in the embedding code. As you do not currently set dimensions, default values of 100% will be used for both the width and height and unless Juicebox can determine when the 100% refers to, you may have problems with gallery sizing. Try using something like:
galleryWidth: '100%',
galleryHeight: '600',
(3) If you have uploaded your entire gallery folders ('live' and 'travel' to your web server), then I would recommend using a baseUrl (to point to your gallery folder) instead of a configUrl. If you use only a configUrl, then the paths to the images within the 'config.xml' file may be incorrect (unless you have edited them manually).
(4) Use relative paths for the configUrl or baseURL. If you hardcode the emmamasseyphoto.com domain in the path, then your gallery will not display if a visitor goes to the www.emmamasseyphoto.com subdomain
I do not see any problem with the containerId entries in the code you posted so you should not be getting any "Cannot find div with id" messages.
Try the following and if it does not work, please double-check that the entire 'live' and 'travel' gallery folders have been uploaded to your root directory.
<script src="/live/jbcore/juicebox.js"></script>
<script type="text/javascript">
new juicebox({
baseUrl: "/live/",
containerid: "livecontainer1",
backgroundColor: "rgba(0,0,0,0.9)",
galleryTitle: "Live",
showSplashPage: "ALWAYS",
showOpenButton: "false",
galleryTitlePosition: "NONE",
showThumbsOnLoad: "false",
imageTransitionType: "CROSS_FADE",
captionPosition: "OVERLAY_IMAGE",
imageNavPosition: "IMAGE",
galleryWidth: "100%",
galleryHeight: "600"
});
</script>
<div id="livecontainer1"></div>
<script type="text/javascript">
new juicebox({
baseUrl: "/travel/",
containerid: "travelcontainer",
backgroundColor: "rgba(0,0,0,0.9)",
galleryTitle: "Travel",
showSplashPage: "ALWAYS",
showOpenButton: "false",
galleryTitlePosition: "NONE",
showThumbsOnLoad: "false",
imageTransitionType: "CROSS_FADE",
captionPosition: "OVERLAY_IMAGE",
imageNavPosition: "IMAGE",
galleryWidth: "100%",
galleryHeight: "600"
});
</script>
<div id="travelcontainer"></div>
