I have a few plugins that show an upgrade available. When I try to upgrade automatically, it shows the following...
Downloading update from http://downloads.wordpress.org/plugin/<em>anyplugin</em>.zip.
Unpacking the update.
Installing the latest version.
Removing the old version of the plugin.
Plugin upgraded successfully.
But the strange thing is that it's not actually upgrading it. The plugin still shows the old version and still shows under Upgrade Available.
I had a similar thing when trying to install a new plugin, it said it was fine but there was no plugin installed. I was able to install the plugin by uploading the folder by FTP.
I tried upgrading to 3.0 and had the same problem, messages saying that everything is fine, but no upgrade actually happening.
I have bumped my memory_limit to 64 in php.ini in case that was the problem, but still no luck.
Would love any help with this, hasn't been an easy issue to find by searching and googling.
