Server 2.5.4 WIP/Client 2.5.2 WIP

Still Testing - There appears to be a problem with the archive function and the save function in general - All my archive settings for all my clients have gone

If I try to make changes to any setting on any tab for a specific client the interface locks up, I can see the progress bar updating but the interface never comes back unless I refresh the page and the setting is not saved.
I can make and save changes to the settings when the drop down is set to Clients.

If I create groups I can edit the settings and click save without the lockup occurring, but nothing is saved.

There is nothing in the logs.
