Edited Posts Will Not Produce Updated Newsfeed Content

I've written a few posts about editing post content - and discuss clearing cache after editing, to see updates.

Generally, my posts reference cached posts content. Sometimes, blog owners need to clear cached feed content, in addition to / instead of clearing cached post content.

There is a difference between post content, and newsfeed content - and how both are cached. Newsfeed cache is not as frequent a concern.

When we provide instructions to clear cached blog content, we reference browser cache.
Clear cache - then restart the browser, and check again.
or maybe
Clear cache, cookies, and sessions (yes, all 3) - then restart the browser, and check again.

Posts, updated after published, may create a problem with the posts newsfeed.

In some cases, updated posts may create an "out of sync" condition with the posts newsfeed, as well as the displayed content.

If comparing post content and feed content is important, you need to synchronize the newsfeed with the posts. This will restart the newsfeed - and sync it with the posts.

  1. Deactivate the blog feeds.
  2. Publish a post - or delete a recently published post.
  3. Reactivate the blog feeds.

Activate / Deactivate the blog feeds, using the "Allow Blog Feed" wizard.

The "Allow Blog Feed" wizard, on the dashboard Settings - Other page, in the "Site feed" section, is used to activate and deactivate the newsfeeds.

Look for "Site feed", and "Allow Blog Feed".



"Site feed" is on the Settings - Other dashboard page.



Open the drop down menu, and note the current setting. If you have "Custom" selected, dig deeper.



There are a few selections, in "Allow Blog Feed". For consistent results, note what you have before Step #1 - and re select them after Step #3.

This blog, like many others in Blogger, is "Always Under Construction".

This post, like many earlier ones, was just published. Now, I plan to spend many long hours, reorganising and tweaking the content, phrasing, spelling, syntax - and correcting typos.

If you wish, you can subscribe to any of several posts newsfeeds - and compare the newsfeed content in each, with the displayed posts content. The older any post is, the more changes will be made.

The more revisions I make, the less this post, and the posts feed, will match when compared. Check it, for yourself.

Maybe one day, I will need the feed, in this blog, be accurately updated to compare more closely to the updated posts. Many of my posts double in size, even after post publish edits are "complete".

If you use email, and other feed subscriptions, to read new posts in this blog, you may be missing out on interesting details, added long after posts are published.

Newsfeed content is published once, as each post is published.

Post content may be out of sync with feed content, because post content and feed content is not updated at the same time.

You can update your posts, when you wish. Newsfeed updates are published when the posts are published - and the cached newsfeed is not updated, when you edit a post after it is published.

When you synchronise published posts content with displayed content, you generally clear browser cache. Newsfeed cache is not in the browser - so the latter instructions won't help with newsfeed cache.

That is the basic procedure for syncing the blog content, and feed content. You may have other concerns, though, that might complicate the above procedure.

The procedure is exciting - but painless.

I initially published this post, without any photos - and we see my Reading List, an hour ago.



And my Reading List, after I restarted my blog feed.



It took all of 5 minutes, including making screen prints of my Reading List - before and after, to restart the newsfeeds.

As always, I'll suggest that you Follow this post - and observe the changes. And watch for changes (unlikely) to the newsfeed.



Many #Blogger problems, when being diagnosed, start with advice to clear browser cache (maybe, cache, cookies, and sessions). Not all problems involved the published posts - some involve the posts feed.

You can't clear feed cache, as you can browser cache, because newsfeed content is not cached in the browser. You can, however, force a newsfeed rebuild, by restarting the newsfeed.

Confusion From Feed Gadgets That Don't Display All Feeds In The List

One of the more intriguing subjects of confusion, about feed gadgets, involves gadgets with more feeds in the list then they are set to display.

Occasionally, in Blogger Help Forum: Something Is Broken, we see the petulant query
Why does my blog disappear from (feed gadgets on) other peoples blogs?

This confusion starts with the question of how often and when we update our blogs, as opposed to how often and when the other blog owners update their blogs. It continues with the little known effect of the difference between how many feeds are in the gadget list, as opposed to how many feeds the gadget is set to display.

A gadget which has 10 feeds in the list, but is set to display only 5 feeds, will display the 5 most recently updated feeds.

A feed gadget will display only the count of feeds that it is set for.

The other 5 feeds will not display - and since the display order will vary according to date last updated, so will the set of feeds displayed. As different feeds are updated irregularly, they become the 5 feeds displayed. The other 5 feeds, updated less recently, will seem to disappear from the display.

This blog has a BlogList with 6 entries (currently) - but set to display the 5 most recently updated feeds. There will always be 1 feed which does not display - and the missing 1 feed, at any time, will be the least recently updated.

Look in the sidebar, for the gadget labeled "THE REAL BLOGGER STATUS - POSTS". Below that gadget, you'll find an unlabeled feed gadget, displaying feeds from 6 different blogs.

What displays, over time, will vary - depending upon recent updates.

If you watch this blog over a period of days or weeks, you'll see 5 feeds display, in an occasionally changing sequence. That sequence, seemingly random, will reflect the 5 feeds most recently updated - and the 6th feed will seem to disappear.

If you are an owner of one of the blogs which are featured, in that feed gadget, you may be occasionally asking yourself

Why does my blog seem to disappear from The REAL Blogger Status, from time to time?

The disappearance will not involve your imagination - just how often you update your blog, compared to how often the other blog owners update theirs.

You can look at the gadgets on your blog - and see the effect on your blog.

Look at the various BlogList and Feed gadgets, on your blog. Do any of your gadgets have a list that's longer than the display number? It's perfectly valid to do this - but if you are doing this, consider that somebody who publishes one of the blogs, that you've featured in your gadget, is occasionally asking himself

Why does my blog disappear from (your) blog?
