technoob I have a bunch of posts on my forum written in Chinese
If you are talking about spam, nany forums are currently facing an increased amount of spam. There are multiple discussions on this topic that you can check: https://discuss.flarum.org/?q=spam. There are extensions that you can use to fight against spam
technoob I am unable to access administration (other than dashboard).
Are you talking about FreeFlarum settings or Flarum's administration? Are there any errors?
technoob My forum has also been disconnected from Google SEO Performance Console.
TBH I don't use Google console, and I don't know their policies, etc..., so I can't help you with this. But again, some (error) message would be useful (e. g.: did your forum suddenly just disappear from the console without any warning?)
