I just upgraded from Gantry 3.0.6 to 3.1.5. Unfortunately, I upgraded manually, downloading the gantry files and then uploading replacing them into the appropriate template folders. It work fine except I get a repeating slash on the "Latest News" list and the search lcon (spy glass) keeps repeating in the bg of the search box. You can see the issues at the following link. I know realize I should have upgraded using Joomla installer (and will do so in the future).
