The best way is to import the original message back into the database and then try it out. I will assume that you are using DF 9.2.1. Try importing this into the database.
This is an export of the original news message. In phpmyadmin, import the file.
First, make a backup of what you now have. This is important.
Second, make a change in line 28 and 44 of the file. Replace the "XXX" with the prefix of your database tables.
Use only a utf-8 editor to make these changes. Do not use windows notepad. I prefer notepad2 or geany.
After making these two changes, import the file.
If you have any problems, report back and I will try to help. I am by no means an expert, but I have had this problem before...
