Hi chaps

One of my DNN 804 instances all of a sudden has a problem. When I attempt to access the module settings of the file manager (digital assets manager) via the ActionButton menu item (my containers use the ActionButtons), it throws a 500 error, the details of which are pasted below. When there are other modules on the same, page, they also do the same thing. However I've boiled it down to the file manager as it is the only module that does it in isolation.

I can get into the settings no problem via the ActonMenu settings link, which is a standard anchor URL rather than a __doPostBack as the ActionButton is.

Regardless of the details, All my DNN instances are identical, same skin, same modules, same everything, except for different websites and content. This is only occurring in one instance. All other modules work fine in the same system.

I've reapplied permissions, reinstalled the module, and tried different skins. Always the same. It's just the file manager that is causing ActionButtons to break and I can't see why.

I'm hoping the exception messages below provide a clue?

Regards
Rob

Bingo! :)

One of the steps that should be performed when upgrading to DNN 8.xx and above is to remove SolPart and any actions menu/button references from ALL of your skins and containers.  DNN adds the actions menu for you.  Action buttons can be supported in many instances, but it's really been deprecated to ensure a consistent user experience across all DNN instances.

Hey Rob:

I get what you're saying, but the action buttons literally have had code removed. While you can sometimes see them working, they are no longer a supported feature. In fact, I don't think they work at all in a clean instance - only upgraded DNN instances.
