Thanks, i only tested it, not on the live board, then what can i do for this problem, you said that my problem occurs because of the wrong import, how can i do this? If you would help, i will be so happy.

When you choose to convert your forum, you must take a full backup of your database, and then convert it in the place.

To test it well, try to duplicate your database on your live site upload vBulletin files to www.yousite.com/vbtest/ and run it with the duplicated database. and convert this test forum. return here with your feedback.

Beta 2 will come soon with new features.

Milad please help me
I get a Error in charset_converter.php :

You didn't excute the attached SQL file!!!

So what did i must to do and how ?

I do all that :
[v]Upload files to their respective locations.
[v]Import charset_convert.sql to your vBulletin database using PHPMyAdmin.
[v]Import the file product product-charset_converter.xml
[v]Refresh your admincp, and go to vCharset Converter->Settings set the Source Charset Encoding and the Destination Charset Encoding.
[v]Go to vBulletin Options -> Censorship Options -> Blank Character Stripper, empty its value and click save.[/list]

You missed the highlighted line.
