Rather than delete the jetpack folder and risk losing something, I imported all the missing files from a zipped copy of the same version. Works great now, thank you!

Ha! That fixed it. There was an empty folder in the root directory called “listings” which now seems to serve no particular purpose. Ah, the joys of updating a legacy website…

Thank you so much for your help!

Soft flush didn’t do the trick. Here are all the rewrite rules. I didn’t see anything that immediately stood out. Any ideas?

listings/[^/]+/attachment/([^/]+)/?$	index.php?attachment=$matches[1]
listings/[^/]+/attachment/([^/]+)/trackback/?$	index.php?attachment=$matches[1]&tb=1

I didn’t mean to imply that it was the theme update that specifically caused the crash. It just happened concurrently. Still no idea why, but it’s back up.

So the issue in the OP stems from the prior use of a custom post structure /posts/%postname%/ that was in place when I installed the plugin. Using this format again, the /listings page works fine, but it becomes domain.com/posts/listings.

Changing permalinks to just /%postname%/ is what triggered the Apache error. Domain.com/listings is how I want to see this page, however.

What do I need to do so I can keep the new permalink structure with just /%postname%/ so I can see the desired page URL?

Thanks so much for your help!

Yeah… my site crashed when I upgraded to the new version of Open Floor Plan.

I’m in the middle of restoring the site from a recent backup now.
