What happened to the Slack description page?
https://www.concrete5.org/slack
This URL is part of concrete/config/concrete.php
https://github.com/concrete5/concrete5/blob/develop/concrete/config/concrete.php#L893-L925
I am planning to send a PR to fix it.
I want to check which are the correct link.
TL;DR. One of client servers set proxy server, and didn’t allow redirect for some reason. I needed to set the final URLs.
