Did you make a database backup first?
While I have a backup from yesterday, I stupidly did not back up after I posted the drafts before I made the update.
I can probably make a database backup through our hosting service.
We have deactivated all plugins and are now activating each one at a time.
It’s working again–an old JetPack component was causing the issue WordPress.com Stats.
Can I ask what your other plugins are/were?
Let me compile a list… there are about 20 or so.
Thank. I’d like to see what other plugins were running before I start flagging up this plugin as a possible 3.4 issue.
So you were using Stats separately and not as a part of Jetpack?
Yes.
Here are the other plugins we used:
Broken Link Checker
cforms
Disqus Comment System
Google Analytics for WordPress
Google XML Sitemap for Mobile
Google XML Sitemaps
Hello Dolly
Pagelines Customize
pageMash
Post Types Order
SEO Ultimate
Simple 301 Redirects
Sociable
StatPress Reloaded
User Role Editor
WordPress Database Backup
WordPress Mobile Pack
Wordpress SEO-Rank
WP-Cumulus
WP-PageNavi
WP-Table Reloaded
WP125
Can we ask you a favour? Can you try deactivating all plugins except WordPress.com Stats and see if the error returns? At this point, we’re not 100% sure that WordPress.com Stats, by itself, is the culprit. It could be a conflict with another plugin.
Unfortunately, I really don’t want to do that because it took quite a bit of doing to make it work again in the back office of our hosting platform. I hope you understand.
