Hmm instead of turning off all clicks can you try commenting out ajaxifyAnchors(); in public/src/ajaxify.js
Weird bug with usernames
Funny story but this bug caused me like half a days worth of trying to find whats wrong. When setting up the nodebb I made an admin with ' in its username. Results were weird to say the least. I could login, but I couldn't actually do anything when I did it, most of the buttons were not working. Basically usernames are sacred for some reason.
