I think adding a user style change settings in nodebb would be a good option. Especially that other forum engines like discourse have this feature for a long time.

To disable this feature, go to the following settings in the admin panel:

settings > cookies > EU requirement

@pitaj Why I shouldn't do that? Other attempts to correct this error did not work.

Did you mean to run NodeBB through sudo? There are no errors when running the forum without sudo, so sudo is no longer necessary.

@paopevil I always run nodebb from sudo.

EDIT: I fixed the error by replacing nodebb files with new ones and running the ./nodebb upgrade command.

I tested npm on my vps and accidentally deleted something, now the forum does not want to start and the console displays a bug visible on the screen. I tried the ./nodebb build and ./nodebb setup commands, but they do not help.

I have a small problem, when entering ACP I do not see any updates of plugins and styles, even though they have already been released.

I go with the suggestion of updating the Font Awesome to version 5 in the future release. Because fontawesome version 5 has a larger number of icons.
