Function calls on pages can be cached as broken ("Content error") but work fine in the editor when previewing, which is confusing and a waste of resources
Closed, ResolvedPublicBUG REPORT

Description

Steps to replicate the issue (include links if applicable):

What happens?:
The last sentence is a Content error.

What should have happened instead?:
Should generate the sentence.

Other information (browser name/version, screenshots, etc.):
Similar on https://www.wikifunctions.org/wiki/User:Denny/Year/dag -- the first Content error under the 1298 heading should show text. The embedded function call itself seems to work.

Would be great to be able to figure out what is wrong.
