Custom CSS not working

[Kathryn Reddie]

• Hi,

We’ve just upgraded our Confluence Data Centre from 8.7.2 to 8.9.5 and the custom CSS doesn’t do its job anymore.

We have Refined for our themes but after investigation with them it appears to be the way Confluence is reading it. 

Im not a developer but have an “ish” understanding of CSS, and we have no Developer with a sound enough understanding of CSS to investigate.

Does anyone know what changed in the way this might be being read? Screen shot attached so you can see the differences between PROD and DEV.

Thanks,
Kathryn.
