How download this free theme? https://www.ubertheme.com/magento-themes/ub-trex/
Thanks for your interest in our free Magento 2 theme UB Trex.
It’s a pity that we could not update the theme in accordance with recent Magento 2 releases, so we temporarily disabled the download access for this theme.
Please take a look at our UB Trex Pro version here to see if it is a good fit for you. This comes packed with advanced mega menu, content slider and quick view modules.
Our team is also working on a 2nd homepage for the UB Trex Pro theme -- Furniture concept, we expect to have this new homepage ready within next week. Just add this for your information.
