title: phpMyAdmin - Error: relational features are disabled
body: <p>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!</p>
