Unable to install extension, the following paths need to be writable...
Note: Prior to MageRewards verstion 1.6, frontend template files were located in the "default/default" folder rather than the "base/default" folders mentioned below.
Unable to install extension, the following paths need to be writable: /.../app/design/frontend/base/default/layout /.../app/design/frontend/base/default/template
If you're using Magento 1.4.x.x you may see this error. If you see these errors it may mean that the folders don't exist. Simply create the empty directories as they are requested and make sure the permissions are writable by the web server user. This is needed even when not using the default/default theme.
