This is the message i receive when loading a new page type in 2.4.
i have a published site made with silverstripe 2.4 that works fine. This site was migrated from a developing server some weeks ago.
Now i create a new page type, Home, extended by Page, for customizing the Home page with an image.
dev/build ok, changed page type in behavior ok, add an image ok, i go to the home page and i see it with my new image. Well.
Some hours later the customer say me that the home page is blank with only the contents and the "Generated with the default ContentController.ss template" message at the end.
I go to the home page and verify the problem.
I remember, i don't do the ?flush=1 on the page!
I do the flush and i see the correct page, but when i remove the ?flush=1 from URL i'll see the blank page again!
Tried to empty the browser cache and tried with various browsers.
It seems that can't write the cache or something similar.
For now i revert back the page type to Page in behavior and all works fine.
