I don't know why this is happening, but none of my content are displayed when logged out. All the content in views, blocks, everything disappear upon logout. As far as I can remember, I haven't touched any permission. In fact I created this project only a few days ago.
I have two jCarousel slideshows and a few views connected with nodequeues on my site among other things; all of them disappear upon logging out. I have already checked all permissions on views, blocks, and everything I could find.
What can I do to resolve the issue?
As an experiment I searched for a content through the search bar, and the page returned said access denied.
EDIT: Problem solved. The solution has been posted in this thread.
