Hey Imran,

I reckon it has nothing to do with your module. More likely it is that there is some file damaged by whatever - maybe oxserial.php?

Best would be to check your installation with an oxchkversion and replace the damaged core files.

yeah i too think there is a error in the core files. i did replaced oxserial.php before. i will try again and see what happens.
