Plugins won’t update when WordPress says they’re updated

by

In a WordPress 3.5.1 network, I have six plugins which have updates available:

  • AddThis Follow Widget
  • AddThis Social Bookmarking Widget
  • AddThis Welcome Bar
  • Jetpack by WordPress.com
  • Visual Form Builder
  • WordPress SEO

I select them, press Update, WordPress loads through it’s update procedure:

The update process is starting. This process may take a while on some
hosts, so please be patient.

Enabling Maintenance mode…

All updates have been completed.

and then I see that I still have 6 updates available, and the updates have not been applied to these 6 plugins.

I have not made any changes to WordPress, and deactivating plugins does not resolve this.

I receive no errors, and the hosting plan we’re on is unlimited disk space.

did you install memcached or apc plugin? If you did, remove them and try it. Probably its caching problem.

Update: I am not sure if this is your case but i was facing this problem when i try to use apc for opcode caching. Basically main problem is fcgi prosesses are not using same cache pool. Here is more details: https://bugs.php.net/bug.php?id=57825 What can i suggest: dont use opcode cache or use memcached for opcode caching.

Update2: It seems we are getting another alternative to apc.. Optimizer+: https://twitter.com/unsalkorkmaz/status/309736703852154880
