If I go to layout in setting I get error 500
For any other options?
Try a different theme.
Also with v2021.009?
The problem only happens in latest version 2012.012. Layout button works fine in 2012.009.
Have tried all themes in settings and same result
Then you can test for it in https://github.com/vanilla/vanilla/releases/tag/2021.021
If present, report via https://github.com/vanilla/vanilla/issues
Not sure how to install this update the last one v012 was installed with istallatron. Automatic updates for minor updates is enabled.
Clone you forum to a staging site.
Ie dont do it on a live site.
Then you can 'play around' and test.
