Found the problem! Case of Form above Function: When you edit the wg-peer at the webform the form seems empty. Just click on the “^” symbol → still nothing → click again →
Succes! pfff,
Maybe this is only with firefox? No, just tried Chromium (linux): same problem.
Long story: I tried new update 7.12, still no luck after 7.11.1234. Removed wg-config, reboot → still no luck. Restored and after some usesless click th peer config showed!
The webfom design is so beautiful it has become un-useable…
I have the same problem (00.07.11.3)—it’s impossible to configure a peer. Clicking the ‘^’ symbol resolves the issue. This is unacceptable for such an important function as VPN configuration. They should include this workaround on the web manual’s wiki page! 
Hello,
I haven’t encountered anything similar on the 7.12 firmware release version. Could you please try checking if the ‘^’ symbol issue persists after updating to the latest version? Additionally, could you let me know which browser you’re using?
Kind regards,
Martynas, let me be frank. We are volunteering bug reporting. Please value that instead of insulting us.
I gave you 2 issues 1 with a solution. The troubleshoot file includes the private key of openvpn.conf. And sending it to you goes via microsoft e.g. shitgpt. An excellent way to get your last troubleshoot file, ever.
Please study how to built a community. Otherwise you may loose customers fast to a company up north to you, were they value a community instead of insulting them.
Sry for the strong wording. I’m dutch.
I do have the same issue with adding and editing Wireguard Peers on a Rutx 10 with Firmware Version 7.13.3. The trick with pressing multiple time the ‘^’ and ‘v’ symbols helped a week ago, but not today. I cannot edit the existing peer and I cannot add a new peer. I tested both with Firefox and MS Edge (both in private mode). A quick look into the firefox developer tools shows only empty comments:
<div test-id="tablerow-wireguard_peers" class="card-content pb-2 md:pb-14" style="display: none;"><!----><!----></div>
I updated the Firmware a week ago, but I cannot tell if I did before or after configuring Wireguard. And I cannot say from which source version.
Kind regards
