Yes you just have to choose different database names (mongo) or numbers (redis)

Oh sorry are you talking about running a cluster of processes for a single forum, or running multiple forums on the same server?

You have to use and download putty where you will write commands to interact with cpanel folders and then you can run and install nodebb .

@damian-gądziak Maybe you can try to debug by adding this in that function console.log(tids.length, uid, new Error('test').stack);
Topics.filterWatchedTids = function (tids, uid, callback) { console.log(tids.length, uid, new Error('test').stack); async.waterfall([ function (next) { db.sortedSetScores('uid:' + uid + ':followed_tids', tids, next); }, function (scores, next) { tids = tids.filter(function (tid, index) { return tid && !!scores[index]; }); next(null, tids); }, ], callback); };
I am guessing the function is called by a huge amount of tids, so the next step would be to find out why and from where.

Looks like your connection to NodeBB was lost, please wait while we try to reconnect.

The common causes for a session mismatch error are usually one of the following:
1. Mis-configured URL parameter in your config.json file
If you have a misconfigured url value in your config.json file, the cookie may be saved incorrectly (or not at all), causing a session mismatch error. Please ensure that the link you are accessing your site with and the url defined match.
2. Improper/malformed cookieDomain set in ACP
Sometimes admins set this value without realising that they probably don't need to set it at all. The default is perfectly fine. This is what the config looks like:

Cookie Domain setting

If this is set, you'll want to revert the setting by editing your database directly:

Redis: hdel config cookieDomain
MongoDB: db.objects.update({ _key: "config" }, { $set: "cookieDomain": "" });
3. Missing X-Forwarded-Proto header from nginx/apache
If you are using a reverse proxy, you will need to have nginx pass a header through to NodeBB so it correctly determines the correct cookie secure property.

In nginx, you will need to add the directive like so:
location / { ... proxy_set_header X-Forwarded-Proto $scheme; ... }

@spwolf unless you applied custom css on your site to make the icons and text smaller, there shouldn't be any difference. Persona theme is used as is on this site. I am sure that there is no custom css applied here.

Prelude: Last year, ran nodeBB under a root user just fine. many months later, system crashed and had to wipe the server. This time on installation, on a new server, ran into various errors. Was told not to run nodeBB under the root user, so --

Creating a new user, and pulling and installing a different instance of nodeBB I am now running into errors with npm install (even using the global command) and generally overall.

Is this still due to file permission issues regarding the first time setting up nodeBB on the new server? Or is something else to blame?

When utilizing nodeBB on the new user, npm gives errors such as not finding modules (even tried removing node_modules directory and doing npm -g install), and when I do get the npm install to not crash, running any ./nodebb command still gives errors.

Does anyone know the issue at hand? I'm thinking of wiping the server, and giving it one more try via not using root from the start to see if the errors can be avoided altogether - if not I may just move on to a different forum system.

Thanks in advance!
