Cannot read properties of null (reading 'remove')

jura43 commented 3 days ago

I fresh installed open-wrt on my Asus AX6000 router. What I configured in DHCP and DNS settings is deleted default instance and created new one with name work. After that I am not able to open DHCP and DNS settings.

Steps to reproduce:

go to: Network → DHCP and DNS

Actual behavior:

I think I am able to reproduce this. I create interface, enable DHCP server, save. DHCP and DNS page still working. But if I edit DHCP settings in interface windows for example I change range of IP addresses and save. Then DHCP and DNS stop working. Here is config before and after editing DHCP in interface menu.

Is there a trackback produced in the browser console? I could not reproduce this.

I manually added config dnsmasq block to dhcp file now I don't have any issues, and not able to reproduce it again. This might seems to be happening only on fresh install, since now I can edit DHCP range with issues. I checked console, and I if remember correctly it was same message as in Web interface.
