Ok, let's try this one last time.

Before you do anything, backup your database!

Go to phpmyadmnin and click on the database name (at the top) in the left window. You will see 5 options in the right hand window. They are:

Structure
SQL
Export
Search
Query

Click on the SQL option and enter this in the big box (just copy and paste):

INSERT INTO setting VALUES ('', 8, 'Minimum Characters per post', 'postminchars', '0', 'The minimum number of characters that you want to require per post. Set this to 0 to disable it.', '', 7);

Hit go and you are done.
