I try two times to hack. dosearch.php give me an error in line 487 after try. In your instructions you write:
## Change this:
$query ="
SELECT t1.B_Number,t1.B_Main,t3.U_Username,t1.B_Subject,t1.B_Posted,t1.B_Board,t3.U_Color,t1.B_Reged,t1.B_Icon,t2.Bo_Title,t2.Bo_Read_Perm,t2.Bo_Cat,t1.B_Posterid,t1.B_Status,t1.B_AnonName,t1.B_Body
but in 6.4.1 the select looks like:
SELECT t1.B_Number,t1.B_Main,t3.U_Username,t1.B_Subject,t1.B_Posted,t1.B_Board,t3.U_Color,t1.B_Reged,t1.B_Icon,t1.B_Posterid,t1.B_Status,t1.B_AnonName,t1.B_Body
I try to remove t2.Bo_Title,t2.Bo_Read_Perm,t2.Bo_Cat from the hack but this dosnt work too. There must be something different.
