Users running a non-download version of Vanilla (pulled from github), on branch release/2019.016 or master from the last 2 weeks should upgrade to release/2019.017 or latest master for security reasons. Downloaded official open sources releases are not affected.
Please upgrade here. These earlier versions are no longer being updated and have security issues.

Fatal Error in PHP.slugify(); when trying to reach /dashboard/settings/branding/

I upgraded from 2.3 to 2.6, and my dashboard would not work at all, at first.

I cleared the cache and tried a bunch of other ideas I found on the forum.

Most of it works now, except when I click on the Settings tab in the dashboard. I get this error message:

Can someone help me figure out how to fix this?

    I guess the key sentence is this: "Call to undefined function iconv()" you should enable the PHP extension iconv

    Also I would recommend to move to a higher PHP version. I start being suspicious of PHP7.0...
