I have to add a new content type to my site for a new feature i'm asked. I already added two of them before (very early in the building of the site, in fact) and it worked well but this time, when i want to add a new node, my new content type doesn't appear in the list of content types (node/add).
It appears in the admin/structure/types page but not in the node/add.
I cleared the cache and rebuild permissions but nothing happened.
I also tried to create a very basic new content type but it didn't appear either.
An earlier exchange on this forum showed it wasn't likely to be the taxonomy access control module.
If I do a clean install of drupal and create a new content type, it works but on my site, i can't do it so i don't think it is because i forgot some step.
May it be because of some problem with a third party module ?
I don't think i have installed very exotic ones but i have some (CKEditor, Taxonomy access control, Piwik Web Analytics... )
I'm turning mad so if someone has some clue, it may really help.
