Hi @Oisijola ,
Apologies. I see the same issue. I cannot save the NTRIP Server 1 details in Base Configuration in the WebUI (“WiFi Config”). There is a bug in the RTK Everywhere firmware. Something broke… 
I have opened an issue for it here. We will try and release a fix for this as soon as possible.
For now, you can set the NTRIP Server details using the CONFIG ESP32 port and the serial menu. Please check you have TeraTerm set to 115200 baud.
Best wishes,
Paul
