After I upgraded to IPS 4 many blog entries contain formatting as shown below:
 

[FONT=Times New Roman][SIZE=3][COLOR=#000000]Some text.....[/COLOR][/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3][COLOR=#000000]Some more text from user.... [/COLOR][/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]

This is probably some formatting from Word when users pasted content from Word. It is possible this happend in the convert from VB4 to IPS 3.x but I first discovered this after the upgrade to IPS 4.

Does anybody know of a way to clean the blog database from this formatting chars?

Nevermind! It suddenly looks okay, this has probably ben fixed with the background build that I can see is going on
