Error: This app cannot be enabled because it makes the server unstable
I'm new to nextcloud. I tried to install the Markdown Editor to have previews, latex and so on. However I get the image below.
Any idea what could be the source of the cause? I'm using nextcloud v22.0.0 on a docker container.
Same problem, v22.1.1, the official latest stable. In my case the plain text editor was shown unstable. I enabled them both, but the Markdown editor doesn't seem to work, ie. the right click on an md file and clicking "Edit in plain text editor" doesn't do anything (or at least it looks like it doesn't). Actually, if I open developer tools in the browser (ctrl shift c), switch to console, then it works. The browser is Firefox 92.0, Ubuntu 21.04 and the latest software upgrade.
