I just install module blog version 03.05.01 on DNN 04.09. When i add module to a page, I got a number of error message similar to:

Error: New_Blog is currently unavailable.

Any idea what happens and how to fix?

Thanks

Hi Sebastian
Your guess seems to make sense, my DB transaction is 800+ MB whereas the database is only 40MB. What could be the problem and how to fix?

Thanks
