Arduino Uno and Nextion display problem

Other Hardware Displays
1

I'm having troubles communicating to the display. All commands from the display (button-events) work fine, but every command to the display (like switch page, set or get text) fails.

I'm using a Arduino Uno R3 clone at the moment, so there is only one serial port available for communicating with the display and for the debug serial monitor. I'm using the Nextion/Arduino library, and I disabled the debug option. But debug info keeps coming to de serial window! Can this be a problem?

Thanks for any help

I am new to nextion.
From what i have been reading, the library is written to use softserial and output debug to hard serial.
If you go to the github site for the nextion/arduino library, there are comments there as to what you need to get rid of debug.
It looks like there are a few sections to disable.
There is also an example using the hardware serial port for the nextion.
