A discussion forum, forum.dark-gaming.com, is experiencing an issue where every theme is forced into full-width mode after installing DarkPixlz’s Modern Theme. @twofoursixeight suspects this issue started after the theme installation. Canapin suggests that the admin may have installed and activated the Discourse Full Width Component on all themes, which could be the cause of the problem. Canapin advises disabling the full-width component as it is an experiment and not widely used. Additionally, Canapin recommends reaching out to the theme author, @darkpixlz, for support on the theme topic, but notes that theme authors may not be obligated to fix conflicts with third-party plugins or components.
Hello. On forum.dark-gaming.com, every theme is forced into full-width. This started happening after the owner of the website installed DarkPixlz’s Modern Theme after a suggestion I made. I am not the owner of this site, @popstarfreas is. Does anyone know any solutions that the owner of the site could try?

Hi @twofoursixeight!
I suspect the admin installed this component and activated it on all the themes:
The full-width component is an experiment and I don’t recommend using it if this is the cause of your issue. Please ask the admin to disable it.
If you want support from @darkpixlz, you should reach them on this particular theme topic: DarkPixlz's Modern Theme, but in general, you shouldn’t expect a theme author to “fix” their theme if it conflicts with another, not widely used plulgin or component (it’s their call).
I’m closing it since you should now have the resources to fix it and it’s specific to a third-party theme that has its own topic. Feel free to reach me by chat or PM if you have further inquiries
