WordPress is loading in an iFrame there, but you’re right in that you’re seeing the wrong thing. I would, at a guess, say that you’ve got a plugin conflict going on.
Here is the full list of plugins that are active on the site (there are none inactive):
– Advertising manager 3.4.19
– Akismet 2.5.3
– Author Avatar List 1.1
– Avatars 10.0
– Email Users 3.4.1
– Enhanced WP-ContactForm 2.2.3
– Event Calendar 2.3beta2
– jQuery Colorbox 4.1
– NextGEN Gallery 1.8.3
– Rich Text Biography 2.7
– ShareThis 5.0.0
– User Photo 0.9.5.1
– WP-Migrate-DB 0.2.1
– WP Shopping Cart 3.7.6.1
In poking around I tried to reproduce so I could look at the contents of the iFrame. The following did NOT trigger the problem:
– Installing a new plugin (WP Supercache)
– Activating new plugin
Installing a new plugin and then updating it reproduced it so the problem seems to be limited to upgrading a plugin.
I’ve added the iFrame source to pastebin here
A cursory glance suggested it might have been nextGEN but disabling that did not remove the problem. Going to try to dig a bit deeper…
Upon closer inspection, this looks to be a problem with WordPress core. The last line of the iFrame is “Just write.” which seemed like it would be unique among all the code in the site so I did this:
root@server:/home/sitedirectory/wordpress# fgrep -R "Just write" *
and got this:
wp-admin/includes/post.php: <div id="wp-fullscreen-tagline"><?php _e('Just write.'); ?></div>
If someone can take a look and confirm (and if confirmed add to an official bug list wherever it resides) that would be great.
Cheers.
Before you’re quick to label this a core bug, did you try turning off ALL your plugins and then updating one?
I don’t see this issue on my test site, which doesn’t mean it’s not a weird conflict with your server and core, but we need to do more testing to be sure 🙂
Good call. Disabled all plugins and went through the update process with one additional plugin installed at a time.
Can run updates flawlessly with all plugins on with the exception of Email Users 3.4.1.
You mean that the problem only happens when Email Users 3.4.1 is installed?
Oh … you did 🙂 http://ww.wp.xz.cn/support/topic/plugin-interferes-with-update-of-other-plugins-in-wordpress-321?replies=1
Okay, just FYI, you could tag this post with ’email-users’ and then not have to make a new one. This one has all the history too 😉 S’okay, though.
