CMS Made Simple Forums

Hallo,
the website of our diving club runs smoothly after upgrading to CMS 2.2.13 and with FEU 2.14.3.4. Further upgrading from FEU 2.14.3.4 to any FEU 3. * version makes the FEU settings disapear. User properties, user groups and users are displayed in the FEU administration. You can log in and log out on protected content pages. All other modules are up to date.
How can I restore FEU settings?

FEU 3.x was a major rewrite. A lot of the configuration settings have moved to file-based entries now, either in your config.php or a json file you can create. Make sure to read the help and the changelogs/release notes.
