I recently upgraded my server and reinstalled 2.5.6. Before I did, I saved the Devices table from the previous install (I don't remember which version, but it was a couple of years old, but definitely V2). Once I installed the new server I restored the Devices table. Everything seemed to work fine until I tried to add new IP cameras or make changes to existing ones. Whenever I click the Save button, I get a message something like "We cannot save your changes now. Please try again later" (may not be the exact text, I'm at another location now and don't have access to the server at the moment).
Any ideas? Could this be because of an old version of the Devices table? A permissions problem? If I need to reinitialize the database and enter all of my devices manually, how can I restore the database to its original state?
