I'm pleased to say the upgrade from 7.2.2 to 7.4.1 went pretty seamlessly,
Except for problems with my Language files.
Problem : WHITE SCREEN
Ive fixed one of them "editbasic" where one of the strings was not attached to a variable.
Once i seen the problem i removed it and that works fine.
How ever i get the white screen with the search language files.
So there must be a corrupt file in there.
I clicked "Update Language File Automatically" on the upgrade procedure.
