Hi, I am having trouble installing discourse at the moment and because of plugins. If I install discourse with the only docker_manager.git, it works fine. But if with plugins such as Discourse Solved then I get a blank page after the installation. Even though it’s an official plugin. so any help?

When you are on the white page on your browser, if you press F12 on your keyboard you should have the dev tools with a console tab where errors log messages. Alternatively can you share the URL of the site presenting this blank page?

Oh, sorry F12 does not work for me. but the logs are below. For the domain, is it okay if I send you in private?

@Falco I commented out everyone plugin even the discourse solved, and then; reinstalled discourse restored the previous backup Everything works smooth. uncommented the official plugins sudo ./launcher rebuild app Again same blank page. So its confusing that why official plugins are blanking out the forum. Can you please provide me a way to install the old version of discourse docker. I am not sure why am I getting this error.

The problem is that discourse-spoiler-alert only works on latest Discourse. Your choices: Move to a more recent branch Remove discourse-spoiler-alert Install an old version of discourse-spoiler-alert (not recommended, because it will probably bit rot there.)
