I just tried to update my forum to the latest 3.1 version (coming of 2.9) and now it won’t launch anymore. There is no error message displayed at the end to installation process as far as I can make out.
When trying to access the site I get this on a constant loop:
I get this message whenever I STOP/START the forum: WARNING: containers/app.yml file is world-readable
I power cycled the Digital ocean server but to no avail.
If you can share a link so we can check it out that would be helpful. But you should also try safe mode, and check for any errors in your /logs or browser console too.
We had a couple of similar reports yesterday concerning the maths plugin, but they should be fixed now.
