Hi Gurus,
I got a fetal issue, Internal Server Error, acutally the sevice is totally down.
Before issue, the ONLY thing I have done is de-installed a plugin (emoj plugin for Android), because this plugin is not nessesary for our site. I de-installed, then restart the nodebb in web ui (http://ip:port/admin). Then every thing is done.
The troubleshooting is done, but nothing intresting is found,
- here I attached the log file, you can see the foot template is not related, and the down time is not recorded.
- I have done restart nodebb as well as nginx
- Tried with reset -t and reset -a, got error from theme

[[email protected] nodebb]# service nginx stop
Redirecting to /bin/systemctl stop nginx.service
[[email protected] nodebb]# service nginx start
Redirecting to /bin/systemctl start nginx.service
[[email protected] nodebb]# ./nodebb stop
Stopping NodeBB. Goodbye!
[[email protected] nodebb]# ./nodebb start
Starting NodeBB
"./nodebb stop" to stop the NodeBB server
"./nodebb log" to view server output
"./nodebb help" for more commands
[[email protected] nodebb]#

Thanks for any kinds of help.
