@nodeham Thank you for all of the help. I will start a new thread for the next problem I am seeing.
Load pages except global header without refreshing entire page
I need this react-like feature that loads pages except the header (because in the global header I put iframe video and I don't want it to be stopped during moving each pages and posts of the forums), is there such a plugin doing this?
With nodebb-plugin-customize, you can edit the header template and put your video there.
Thanks, it worked!
