Hi,
How do I get rid of the error message please, that appears on ALL pages in my confluence whether old or new?
The following macros are not currently supported in the header

Back in the day, I added a CSS style for inline code. I would very much like to remove this now, so the error goes away.
I've looked at a couple of other questions related to this, but "Header and Footer" no longer exists under Space Settings > Look and Feel area.
I definitely do not want this style any longer and just want the message gone. if this is something that I can do, I'd very much appreciate some instruction. If not, i'll hit up Atlassian Support.
Thank you very much,
Luke
