OK, just did a manual install of 18.104.22.168, but I still get the downloader when I go to frontend, and I get the following error when going to backend:
Too many redirects occurred trying to open “http://8ightpowerbands.com/shop/index.php/admin/downloader”. This might occur if you open a page that is redirected to open another page which then is redirected to open the original page.
The manual install was successful. When I replaced the “app”, “media”, “skin” folders with the HelloMix files, the issues came up.
