Selecting all plugins to update would update only one

Hi Community,

I′ve read several posts regarding problems updating WordPress Plugins but I couldn’t find anybody with the same problem I am facing.

I can see several plugin updated pending, if I choose all of them and select the Bulk Action > Update, the returned message is:
——————-
The update process is starting. This process may take a while on some hosts, so please be patient.

All updates have been completed.
——————-

The problem is that no updates at all are being done although the received message.

Things I already tried:
– Disabling one plugin at a time to see if the behavior changes, no, it didn’t.
– Changing the Theme to a default theme, didn’t help either.

I′ve done a lot of research and spent a lot of time trying to fix this, but I cant find the problem.

Any help or ideas would be really appreciated.

Thanks!
