Hi All,

I'm new to DNN and am stucked at a simple (I suppose) problem on module, particularly on Event (and Blog as well).

I am getting the following message, when trying to Add an Event. I tried asking Google and seems like it has something to do with file permission...? I have no idea on how to proceed in resolving this issue. I'd appreciate it much if any of you can give me a heads-up on what can I do next to resolve this. Any error logs I can check? Any debugging steps I can try?

Thanks!!

Error: Edit Event is currently unavailable.
