Thanks again for the reply
I don't want to get sidetracked with the action buttons. They work fine and otherwise have nothing to do with the fault. It actually occurs when any link or button that uses a __doPostBack is clicked on the same page as the DAM module.
I've confirmed that the portal file system (skins, modules, bin and all) is not at fault by making a duplicate copy of the faulty DNN instance, confirming that the issue occurs, and then restoring a database from a working DNN instance. With the restored database, the problem no longer occurs. That tells me it's a data problem.
I've now restored the faulty database and I'm going to get into the db and wipe out data until it no longer happens or the instance dies. Any suggestions around that task are appreciated.
Regards
Rob
