problems with breaks even after changing in config file

My problem is that even after I changed the config file into:

FCKConfig.EnterMode = 'br' ; // p | div | br
FCKConfig.ShiftEnterMode = 'p' ; // p | div | br

The results are still not the way I put it in the textfield of FCK Editor. For example:

This is a test.
This is a test.

This is a test.

The result I get after saving into database is:

This is a test.

This is a test.


This is a test.

Can someone help me out with this problem? Thanks for your help!
