what is this, what should it be  and how can i change it in the right state?

It appears the language file for the Payment module did not get compiled.  You can try recompiling it by going to modules, add and manage, and then select the module from the list and click recompile language.  If that does not fix the issue, then either the language file is missing or something else is happening to prevent the language file from being compiled.

This is your second post on this.  If you are seeing this problem in all your modules, then don't make a thread for each one since you most likely have a common issue that is affecting them all.

You should have also mentioned in a single topic that after upgrading you are experiencing language issues and then shown a few examples.  Please don't create a new topic for each module you are having issues with; there is most likely a common problem as the cause or you might just need to recompile the language for each affected module.
