LCD problem

[Andre_Pretorius]

Thanks guys
Changing to define osc 48 fixed all the problems, LCD serial everything. Now for the question -- Why???
On all the other projects you set the define to the cristal freq. but now you set almost 1.5 times higher.

I am confused can someone PLEASE explain this to me

Well, look in the datasheet, Oscillator section, and check the available configuration fuses setting. Yes they're a bit tricky to understand...

From there, you may discover that you can even have a processor speed of 48MHz using a 4MHz crystal... this is accomplished by the internal set of clock divider and PLL.

As Microchip's bootloader set the Config Fuses for an internal processor speed of 48Mhz, your code must follow it.
