Hi,
I've noticed that , this error comes in the following scenario:
1. Imported the spaces and files using an ACP.
2. After importing, I felt that those are useless and I decided to delete them.
3. At this time, I get the above mentioned error, though the spaces are empty or not.
I am not sure if this is a problem with the ACP that I used, but I tried creating some spaces manually and deleting them. This time I was successful. Anyway I was totally confused. :?
I had no option other than deleting the database and recreating it. Now I am running with this new database, but I am sure that if run my old ACPs, I will land in the same stage.
