I created a test topic, but the option does not appear to mark the answer as the best, what can it be?
AI-generated summary
The discussion revolves around installing the Discourse Solved plugin to mark accepted answers. wiliamjoaquim initially reported that the option to mark the best answer was not available. codinghorror explained that only the post author and staff can mark a post as a solution using the Solved plugin.
wiliamjoaquim asked for help installing the plugin, and david provided a link to the plugin’s instructions. wiliamjoaquim struggled with the installation process, and cpradio provided step-by-step instructions to edit the app.yml file.
The site went offline during the rebuild process, but cpradio assured wiliamjoaquim that this was normal. After resolving some issues with the app.yml file, wiliamjoaquim successfully installed the plugin.
However, the solution icon still did not appear, and david explained that the plugin needs to be enabled in each category’s settings. tophee offered advice on carefully following instructions and understanding the process to avoid future issues.
Do you mean for the solved plugin? Only the post author and staff can mark a post as the solution.
How do I install this plugin?
See the first post here for instructions:
Could the complete command be put? How to launch app.yml?
You need to SSH into your server, and edit your app.yml file (it’s just a text file)
It is located in /var/discourse/containers/.
I’m a little layman on this, if I pass SSH access, would you do it for me? Haha
I can’t, but if you post in Marketplace someone might be able to help
Use this eating to access?
cd /var/discourse
/containers/app.yml
This is not working 
You are missing a command there.
cd /var/discourse
sudo nano containers/app.yml
Scroll to the bottom (using Page Dn), till you see the last - git clone ... command
Then add a new line, use spaces to ensure your - lines up (must be spaces, do not use tab) and paste the new git clone command
git clone https://github.com/discourse/discourse-solved.git
Then press CTRL + X, answer Y to save, press enter again (I think), then once at the console run
sudo ./launcher rebuild app
This might help:
I did what you taught me, the site went offline, is it normal?
Yes, it will go offline during a rebuild. It will be back up once the rebuild completes.
Would seem not, it seems your app.yml has an invalid character in it. On line 98. You can use nano to edit it again, and press CTRL + C to see what line your cursor is on. Find line 98 and take a screenshot of that area. If there is any sensitive info, such as passwords or email addresses, be sure to use an editing tool to blur them out.
I think what @cpradio meant was to go back into your app.yml file as per above
The site is still offline, will I miss it?
