When I switched 2 of my sites over from 2.92 to 3.0 I have noticed some issues with the upgrade automatically links for a plugin. When a new updated plugin is found there is a link next to the plugin to upgrade automatically. When clicking on this link I get a screen showing it is downloading but that is it. The screen never updates to say it was successful and plugin was reactivated as in 2.9.2. See the screen shots for more information
As you can see from screen shot #3 the updated plugin was installed but not activated.
I checked on my other 2.9.2 site and I don't have this issue.
My upgrade procedure was as follows:
From 2.92 I downloaded the 3.0 beta 2. Unzipped the file. I deleted from my wordpress root directory directory, wp-admin, wp-includes. Then I selected all the new files except the wp-content directory and uploaded the new files overwriting the old ones.
I then completed the install through the login dashboard.
I have since used the automatic upgrade to change to 3.0 rc1 and 3.0 rc2.
They all have the same issue as described above.
During my search for this problem I could not find anything. But as always it could be the wrong key words.
Thanks if someone can help me.
