@girish I created a 404.html both in the file manager and in the git repo---nothing.
@robi checked I took a look in the file manager & terminal and there were no clues as to why the repo was there but the files were not
I did find a workable solution: I ended up cloning the repo into /app/data/ and then renaming the directory to 'website' and now it's live again.
I seem to have to pull manually from the app's terminal though, and can't just push to the 'page' remote from my local machine. Is there a git command I can use in the /app/data/website directory to have it stay synced to the 'page' remote like the cloudron app should be doing anyway?
