But for most of the pages on the wiki, when i log out, i can't edit them and it says that i need to be an autoconfirmed user, fandom helper, wiki representative or wiki helper to edit them, THIS MEANS THAT THERE IS A DEFAULT PROTECTION LEVEL ON THE WIKI AND THE DEFAULT PROTECTION LEVEL IS SEMI PROTECTED?
Just link the wiki here. And by default you should be able to edit all pages. Maybe your wiki has an overzealous admin. But we won't be able to say for sure until and unless you give us a link to the wiki.
