Try safe-mode
You can get to [safe mode](https://meta.discourse.org/t/53504?silent=true) by adding `/safe-mode` to the url like
`your.site/safe-mode`
You should see a bunch of options like:

Actually, I had added a new plugin today - [GitHub - discourse/discourse-data-explorer: SQL Queries for admins in Discourse · GitHub](https://github.com/discourse/discourse-data-explorer.git)
After that I rebuild app. it was showing \*\*\* system restart required \*\*\* when I login console. I turned OFF and ON again my digital ocean droplet.
Now forum is showing Oops message.

Would love to help but this is over my head.
I’d say give it a go without any plugins just to rule that out.
No worries though, I’m pretty sure someone else will step right in and help.

What’s with the dollar sign$ at the end of the github repo paths that look like regex “ends” ?
Did you break the yml file when you edited it?

Nothing that is the error during copy from SSH.
By the way, I have removed those all.

did you try to go back to the app.yml file you had before? whenever this sort of thing happens to me it tends to be because of a typo in changes I make in that file.

No, I have checked that. I had only added a git clone url to the `app.yml` that is removed.

ok - but you didn’t then add a stray letter or character elsewhere in the app.yml file? I have made this mistake myself and paid the price. now I always keep a backup of the file just in case. 🙂

Can you send me the content of `app.yml` file to check it out. I have edited it more than 10 times in past.

Like @tobiaseigen said, if you added or removed a space somewhere, that could be the problem.
It may also be the case that some plugin that used to work is now causing a problem. That flags plugin hasn’t been touched in a year.
If this is an emergency that you would like to throw money at you can [pay me to fix it](https://www.literatecomputing.com/product/rebuild-your-droplet/).

this might help:

For now, when I try to run set up, I get this message. Port 80 appears to already be in use. If you are trying to run Discourse simultaneously with another web server like Apache or nginx, you will need to bind to a different port See https://meta.discourse.org/t/17247 If you are reconfiguring an already-configured Discourse, use ./launcher stop app to stop Discourse before you reconf…

That’s a good idea. Another way to do that would be to
```bash
cd /var/discourse
cd containers
mv app.yml app-safety.yml
grep DISCOURSE app-safey.yml
cd ..
./discourse setup
```

I think this all will remove data and install a new discourse 🙁

No, it won’t.
It does assume that your data is stored in `shared/standalone.`

Will it solve the problem?
