I just did a fresh install of Magento ver. 188.8.131.52, and uploaded the HelloMinty theme files to my server. Everything seems to work fine, however, while configuring the CMS Static Blocks and the “Home” Page, I noticed that the “Homepage” layout template was not available in the dropdown menus. Only the default “Empty, 1 column, 2 columns, etc.” are visible.
I set the whole cache to disabled while making changes, and even then I still refresh it when things aren’t going as planned. I don’t think that was the problem, although Magento does some weird things when it comes to updating itself after code or layout changes.
I basically ended up installing a clean copy of the theme, overwriting my changed copy, and that did the trick. Now I’m reapplying the changes one by one. I’m still not sure what happened.
