I have a decent amount of experience with working on a wiki, however the top navigation bar has not been working for me. I know that if you edit it, it takes a few minutes to update the bar across the wiki. However, today after working on the top navigation bar, and copying the code from https://community.fandom.com/wiki/MediaWiki:Wiki-navigation (just messing around), and now the top will only have the one I copied, and even after deleting it and replacing it, it will not change after 3 hours. All the tutorials to work on the navigation bar only are for the old format that doesn't work on the new format. Does anyone have ideas on how to fix the issue?
