Regions not showing in block region demonstration My regions are not showing anymore in my block regions demonstration. However they are showing in my block layout.




The regions also not display on the pages. I don't know what I did wrong. I checked the .info.yml, libraries.yml and .theme but nothing helped. I cleared the cache and still it wouldn't display.


What I did:


Cleared the cache
Checked info.yml 
Checked .theme
Checked .libraries.yml
Added blocks to the regions in question
It's pretty hard to troubleshoot, but I would really recommend looking at the .theme file again. It sounds like the region is not configured/configured incorrectly there. Maybe post that here?
