Hi @MattMattV, Thanks for your report. I’m not able to reproduce the issue and changing the link preview settings in system console works fine. Can you share which version of Mattermost you’re using? Perhaps you could try updating to the [latest version](https://about.mattermost.com/download/) released on March 16th and let us know if the issue still persists for you? ---

I just upgraded to 3.7.2 and the issue persists. 😥 ---

I followed the install guide on an Ubuntu 16.04.2 LTS host from OVH, I also followed the guide to use nginx as a reverse proxy + let’s encrypt automation. If it can help I can provide a System Admin accont since my server is not sensitive at all, it may be easier to debug and see what’s going on. ---

@MattMattV Does the issue reproduce for any other System Console settings, or only for Link Previews? Also, which of the two Mattermost versions did you install: - Team Edition: `https://releases.mattermost.com/3.7.2/mattermost-team-3.7.2-linux-amd64.tar.gz` - Enterprise Edition: `https://releases.mattermost.com/3.7.2/mattermost-3.7.2-linux-amd64.tar.gz` ---

```auto ls -la config/config.json ``` Is the file owned by the same user the process platform is using to run? Perhaps you are running it with an unprivileged user while the config.json file is owned by root which would not let you change the file itself. ---
