No WireGuard "Save settings" "Stop WireGuard" buttons

[HansiJung]

Hi,
I just set up a new Raspberry Pi 3 B with RaspAP V2.9.6.

In the WireGuard Dash I can upload my configuration but in the bottem line I can not see any "Save settings" "Stop WireGuard" buttons.

In the upper left corner wg up is not green.

Aftre reboot I can see on the other Server that the WireGurad is conected, but on my RaspAP it is not up.

Any idea?

If the save / stop buttons aren't appearing, it's possible that something related to your config is creating a PHP error. Try executing the following in the shell:

sudo tac /var/log/lighttpd/error.log | grep -m 1 'PHP Fatal error'

Ahh, there ia something

2023-10-23 17:36:10: (mod_fastcgi.c.449) FastCGI-stderr:PHP Fatal error: Uncaught TypeError: htmlspecialchars(): Argument #1 ($string) must be of type string, array given in /var/www/html/templates/wg/general.php:96

This part of the template outputs the DNS value $wg_srvdns that is parsed from your wg config. DNS values usually take a form like this:

[Interface]
Address = 10.0.44.2/32
PrivateKey = [private_key]
DNS = 1.1.1.1

RaspAP is interpreting this setting as an array, instead of a single string value. It should catch this before passing it to the template, but I'd start by checking the value in your wg0.conf file.

Yersterday there was an update to V2.9.7.

I reinstalled it.

Still the same problem

start by checking the value in your wg0.conf file.

It looks like this:

[Interface]
PrivateKey = [PrivateKey]
Address = 192.168.178.209/32
DNS = 192.168.178.1

[Peer]
PublicKey = [PublicKey]
PresharedKey = [PresharedKey]
AllowedIPs = 0.0.0.0/0
Endpoint = [Endpoint]
PersistentKeepalive = 25

Yep, it's a bug. Thanks for reporting this
