hey yakidank thanks for reply as you told to explain my problem in detail,it is as below
i today tried to change my host. files and database was successfully transferred..
but when i opened site at new host the and published news disappeared..i also cant login, it says incorrect username and password..
this is how it looks >>>>> http://sukrut.0fees.net.
this is how it should look like >>>> http://sukrut.x10.mx/pligg.
as we can see i think there is some problem with database connectivity but i checked twise everything including dbconnect.php and settings.php everything seems to be ok.
thanks in advance...
