		Having taken a look, I’d guess your theme is doing that – there are many inline css rules applying to mobile.
Sorry beyond help from me. 
		
	 
	
	
	
 
		
			
	
	
		
		hello.
The theme has been canceled.
Please see once if this is mobile compatible.
		
	 
	
	
	
 
		
			
	
	
		
		I can only suggest
it could be a theme or plugin issue
			Themes
			As a test switch to a default theme such as twentytwenty, and see if this fixes.
			Plugins
			If that doesn’t work, also deactivate all plugins apart from bbpress and see if this fixes.  if it does, re-enable one at a time to see which is causing the error.
			If you cannot do this to your site (say because it is live) then use the ‘troubleshooting’ features of this plugin to let you test without affecting other users
Health Check & Troubleshooting
			Then come back
		
	 
	
	
	
 
		
			
	
	
		
		hello.
I canceled all the plugins and got the design I wanted, and I’ve been feeling good for the last few days.
But it came suddenly.
I didn’t do anything in particular.
But suddenly the mobile design collapsed. What may be the cause,,,
There was no change until last night.
		
	 
	
	
	
 
		
			
	
	
		
		Ah,,
I found the cause
I have a different question,
.bbp-author-avatar
I want to increase the size of the avatar here, but it doesn’t work.
What should I do now,,,?
