Similar to but the solution doesn't work: How to solve "This version is not compatible with Drupal 7.x and should be replaced" error?
I've followed everything I can find but a basic custom theme in sites/all/themes is not working at all. Here is my .info:
name = Custom
description = Custom custom theme built with Stark
package = Core
version = 7.1
core = 7.x
regions[content] = Content
regions[main_nav] = Navigation
regions[sub_nav] = Sub Nav
regions[landing_large] = Front Large Box
regions[landing_ads] = Landing Ads
regions[landing_ad_bottom] = Landing Ad Bottom
regions[landing_books] = Landing Books
regions[home_first] = Home first
regions[home_second] = Home second
regions[home_third] = Home third
regions[search_box] = Search Box
regions[search_ad_box] = Search Ad Box
regions[content_first] = Content First
regions[content_second] = Content Second
regions[content_authors] = Content Third
regions[content_blogs] = Content Fourth
regions[sidebar_right] = Sidebar Right
regions[footer_first] = Footer First
regions[footer_second] = Footer Second
regions[footer_third] = Footer Third
regions[footer_fourth] = Footer Fourth
regions[copyright] = Copyright
regions[shopping_cart] = Shopping Cart
stylesheets[all][] = css/layout.css
I've tried with and without Package, it clearly has defined the version, the core version, the content region...what is it? I copied the .info file from a theme that works perfectly and this is the .info of that other theme verbatim.
