| Sep 1, 2020 at 12:58 | comment | added | sonfd | Which version of drupal? Which cache modules are in use? Does this happen on a fresh install of drupal? Does this happen with the bartik theme? Do you have custom code rendering or saving nodes? Do you have custom caching code? Please check these things and add all of the information to your question. | |

@leymannx as far as I can tell, when you unpublish a node, the cache_table entry for that node's url alias has it's tags cleared and checksum set to 0. When you publish the node again, Drupal cannot invalidate the page cache entry because there are no tags to target. So the page cache entry is just hanging out there, resulting in stale content. At least that what seems to be happening here.

| Sep 1, 2020 at 12:30 | comment | added | sonfd | Can you add which page caching modules you have enabled, also whether there are any external cache mechanisms, e.g. varnish. | |
| Sep 1, 2020 at 12:26 | comment | added | sbrattla | @sanzante it's a plain node view. No views or anything else fancy involved. | |
| Sep 1, 2020 at 12:26 | comment | added | sonfd | You didn't add how the node is being displayed. The cache tags only invalidate cache for things when the tags are appropriately added to render arrays. | |
| Sep 1, 2020 at 12:25 | comment | added | sanzante | Are you on the node view or are you talking about for example a view where the node is displayed? | |
| Sep 1, 2020 at 12:24 | comment | added | sbrattla | @leymannx updated question to reflect that. If this is already built in, it may be a bug then. | |

I'd like the page cache for any given node to invalidate when that node is changed. – that's already built in. But it depends how and where exactly this node is being displayed. You probably need to update your question clarifying that.
