My Database has been working fine until recently. Now I Can't add or delete records. I checked all the permissions and they seem to be correct. It all seems to stem from the format errors that appear internally.

For example, here is the error message I get when I try to delete one of the records with format errors:
The records with the following keys were not found in the database.


When I try to add a record I d not get an error message. It lets me go through the whole process of adding the record, then when I submit it for posting, the verification page is completely blank. When I log out to view the record, it has not been added. Any help would be great. Thank you.
