Where can I find the MySQL\'s logs (errors, queries, etc.) in the phpMyAdmin interface?
I am using phpMyAdmin version 4.2.11. At the time of writing, my Status tab looks like this (a few options expanded; note "Current settings", bottom right):

Note, there are no directly visible "features" that allow for the enabling of things such as slow_query_log. So, I went digging on the internet because UI-oriented answers will only be relevant to a particular release and, therefore, will quickly become out of date. So, what do you do if you don't see a relevant answer, above?
As this article explains, you can run a global query to enable or disable the slow_query_log et al. The queries for enabling and disabling these logs are not difficult, so don't be afraid of them, e.g.
SET GLOBAL slow_query_log = 'ON';
