Yes
I just removed all themes .. kept only the default one ..
I looked into theme_fields, it was empty .. good
themes table has only one theme ..
now I’ trying to enter the app
sudo ./launcher enter app
and do full assets precompile …
now I’m trying to look into .. why the css variable --secondary is zero : rgba(0,0,0,0) ..
Even with that .. still same issue 
Mmmmmm and It seems whatever theme I’m using .. it’s just not picking any color pallette ..
I made sure of the settings ..
You say you set to the default, but I still can see the Mint theme and nskht-mn-mint-light color scheme, I’m confused 
[EDIT] now I see the default theme with dark color scheme, but yea, still not color definitions.
Did u access my website ?
https://www.yasater.com ..
It’s set now for default theme … unlikely it;s a caching issue ..
Ah, yes the color pallette is a copy from a previous one .. will set it now to light ..
Yes, even the default color scheme is not being generated.
I guess you are using the latest Discourse version now? It’s quite a mystery.
oh my that is very odd
Yes indeed .. the latest ..
I even removed the Default one .. no themes at all .. then realized nothing changed !!!
So the whole theming/colors are not working at all ..
Reinstall a fresh theme air-theme .. set a new colo pallette .. Also nothing changed ..
What could be the reason !!
Currently trying to flush the redis .. then rebuild .. let’s see
Can you check /logs to see if you see any errors?
Yes I did .. nothing suspecious .. all normal ..
Did you switch from tests-passed?
Have you tried to use /wizard ?
Yes I used /wizard .. whatever I do .. the color part is not reflected at all ..
I don’t know what to do now … something is b roken but can;t figure it out
I’m using the latest discourse docker .. after installation with no issues, I noticed there were some issue with background colors, as in this screenshot:
I’ve posted my issue here and got a lot of suggestions, none worked.
After inspecting what is going on .. it seems the css variable --secondary is not defined any where ..
How is this variable defined, and where ??
I’ve merged your new topic, there is no need to have two topics about the same issue 
Did you try with safe mode?
Hi yes, sorry I misread the topic and that was already asked.
Did you try reinstalling and restoring a backup (preferably on a test server)?
just moved to another thread .. (same question)
Here what I had to do eventually ..
I installed another fresh discourse docker .. it worked prefectly .. no issues .. then I let me current discourse uses a fresh postgres database .. it workled perfectly .. so it seems some settings were messed up from the previous installation .. the tables I suspected were: theme* and site_settings .. I treid to fogure out which setting might cause this .. no luck .. or this will take a hell of time ..
I was searching on how to reset these settings tot he default values and/or remove unused one ..
eventually I neded up .. for whatever theme I want to use, I just fork it on github, update it by adding the color definitions manually in one the scss files .. and the install it from my admin interface ..
