Nodebb is messed up

[ChrisPy]

Hi,

My nodebb install will not let me post new topics or reply to comments.

I thought it was the theme I was using so I decided to install another one. Now I can install anything. I get this error --> https://pasteboard.co/GBQQYtw.png

I know it says there's an issue with the vanilla theme, but I have uninstall and reinstalled it and it didn't work.

What can I do about this?

That is not how you install themes.

@yariplus how do I do it?

Using the Plugins => Install Plugins => Find Plugins page in the admin panel.
