Exactly my issue, good to see there is a fix, will wait for 0.9.1
Thanks

Should I open an issue on github for this?
I have been browsing the issue list but haven't seen this one.
Looking for a way to help you fix it, let me know if I can do anything, I checked with developer mode on chrome but no error shows.

Redis now secured.. I should have read that before, thanks I had backup!

Problem 2 still exists, if you ever experimented that before
Basically, just reading any post and hitting the BACK button in the browser, minor bug for now.

Seems you are right

By default Redis listens for connections from all the network interfaces
available on the server. It is possible to listen to just one or multiple
interfaces using the "bind" configuration directive, followed by one or
more IP addresses.
Examples:

bind 192.168.1.100 10.0.0.1
bind 127.0.0.1

can't believe it's open to everyone by default? hmmm

Hey Julian,

How can you be sure someone flushed the data?
I added log support to redis, so if it happens again, I will check the log to see what happened.

Redis-server should only be accessible from the server, and it's a VPS (only I have access).
Looks more like redis overwrited dump.rdb with some kind of bug, will investigate..
Here is my redis.conf

I wake up this morning and the forum is down. I tried restarting nodebb and redis but not working (empty forum, like the DB was flushed), if you have any idea.. Thanks

Problem 1:
Something happened to the database, it's 18 bytes and should be 2MB. will restore.
What can be the cause of this?
See this screenshot

Seems like it's a redis problem, I checked nodebb log and it shows no error?

this is the restart I manually did this morning :

Problem 2:
I restored the dump.rdb I saved yesterday (thank god)
and having some issue at the moment, like this show up in the top bar when I click on a topic and hit BACK in the browser:

edited, will open a new post for this Thanks

I should probably install the anti-spammer stuff. I just have captcha but noticed some random user registering (porn site, etc.) WIll look to do that in the future.

Exactly! Learned a lot today with your help. I was afraid to upgrade but once you know how it works it's pretty easy.
Keep up the good work, nodebb rocks

I have a backup every day of dump.rdb
About security, I haven't done much since the database and the forum are on the same server, in a non public area. Should be enough? Thanks!
