This is something I think people from b2evolution should consider changing.
I created a blog and configured a specific media location but did not created the respective folder physically.
Sudenly, every other blogger was blocked from uploading their images, getting the error message: "The blog's media directory «media/tv_janela/» could not be created, because the parent directory is not writable or does not exist".
Should not be reasonable that only the "tv_janela" blogger be advised of the problem when he would eventually try to upload his images?
