When I log-in to the WordPress dashboard, it shows there's a new plug-in update. Most of the time it shows there's a one or two new plug-in updates. When I click on the update link, it doesn't show any update? Also Plug-in page doesn't show any update.
Apart from that, sometime WP admin bar shows there's a one plug-in update, but plug-in tab shows two plug-in updates. But actually there's only a one plug-in update. (First screenshot).
Sometime Admin bar shows there's a plug-in update, but plug-in tab doesn't show new update notification (3rd screenshot).
I don't have any pirate plug-in. All of them are downloaded from the WordPress dashboard. There's only one premium plug-in, its WordFense premium. It's also a genuine plug-in.
These screen shots are not any photoshop modifications. Anybody has a good idea what is the reason?
