Uart1 & Uart3 not working at same time in pic18fk67k40

Question

I am using PIC18f67k40 with internal clock at 8Mhz (IDE 7.5). I did led blinking and simple UART1 transmit that works fine.

Next while trying UART1 & UART3 at same time, only UART1 works... (UART1 init first then UART3 init) if i changes init order UART3 works but UART1 not works,

Pins for UART1 : (Tx=RC6 & Rx=RC7) and UART3 : (Tx=RE0 & Rx=RE1) I'm using default pins only, is there Peripheral pin mapping necessary or what should i do ?

Sample code

Please include the code not as image. Whats inside yout init functions? — Mike, Aug 12 '19 at 07:03
that's all mikroc predefined functions, anyway problem solved, thank you — Ram Shivas, Aug 14 '19 at 04:52

Problem solved, we have to use UART_Set_Active() function before using them when we deal with two or more UART'S.
