thanks for keeping the broken portal up. I hope we can figure out still why it's broken. I see the behavior on the search tab as you point out, but the browse tab does work. I opened the 'live map services' folder in the browse tab and noticed some broken images (they should appear next to the title).
the image element is:
<img title="Live Map Services" alt="Live Map Services" src="/inspire.dundeecity.gov.uk/catalog/images/ContentType_liveData.png">
also: the link on the item to the preview page is:
notice the double domain and lack of 'geoportal_broken' in the URL. this should give a hint as to what's wrong in the configuration. check that reverseProxy.baseContextPath is set to the user-face full URL, not a relative URL.
Thanks for that - I updated the baseContextPath and that helped improve things and I can access the browse tabs.
