问题
When I want to create a relation between two tables in designer mode with phpMyAdmin 4.3.8, it gives me an error saying: Error: relational features are disabled! When I try it with 4.1.4, it works just fine. I can't seem to find where I should change the settings to be able to create relations in designer mode. Any idea? Thanks in advance!

Convert your table/db engine to InnoDB using
ALTER TABLE table_name ENGINE=InnoDB;

I had the same issue, it was because I didn't have a database on the mysql server for pypMyAdmin settings.
So you may need to update your PMA settings database or create one...
There is a guide on how to do it here

I have faced the same error I didn't create any PMA Users I just upgraded the version of phpmyadmin to latest version and everything worked just fine
here is the link for downloading and for me it was 4.6.0
https://www.phpmyadmin.net/downloads/
and for me I was working on MAMP Pro so I just did :
- I stopped the server (MAMP Pro).
- I copied the file (config.inc.php) from the old phpmyadmin folder to the new one.
- I replaced the older version with the new one in ("/Applications/MAMP/bin/").
- I copied the same new version folder to ("/Library/Application Support/appsolute/MAMP PRO/") because I am working with MAMP Pro not MAMP.
- And then I restarted the server (MAMP Pro ) and everything worked just fine.
I hope it will work for you as well.
