I've just noticed a problem on a WP 3.5.2 install running the latest version of Jetpack; it would appear that if a non-administrator user (such as an Editor) tries to view all posts, a 500 Internal Server Error is generated. Admin users are unaffected and can operate all functions of the site as normal.
So far, I have tried the following to see if they might fix it:
- Reset Plug-ins Folder
- Delete, then reinstall Jetpack
- Reupload wp-admin and wp-includes folders from a clean install of WP
- Set the Theme to Twenty Twelve
Sadly, none of the above seem to have helped - the error starts to occur only when Jetpack has been "connected" to my wordpress.com account.
Has anybody else come across this behaviour at all? My guess is that it may have been caused by the most recent update as it didn't happen before! Either way, I thought I had better report it, and if anyone has any ideas as to anything I could try to fix it, that would be great!
