Saving option failed. IPv4 only for Server IP lightspeed issue fix

Saving option failed. IPv4 only for Server IP

The error message “Saving option failed. IPv4 only for Server IP lightspeed “ issue is typically caused by trying to save a Lightspeed configuration with an IPv6 address for the server IP. Lightspeed does not support IPv6, so the configuration will fail to save.

To fix this issue, you need to change the server IP to an IPv4 address. You can do this by editing the Lightspeed configuration file. The location of the configuration file will vary depending on your Lightspeed installation, but it is typically located in the following directory:

/etc/lightspeed/lightspeed.conf

Once you have located the configuration file, open it in a text editor and change the server IP to an IPv4 address.

For example, if the current server IP is 2001:0db8:85a3:0000:0000:8a2e:0370:7334, you would change it to 192.168.1.1.

Once you have changed the server IP, save the configuration file and restart Lightspeed. The error message should no longer appear.
