If you run phpMyAdmin under Hiawatha, you might encounter one annoying error.
When trying to sort MySQL table content, it simply says Error 403 in a small pma error window.
The fix is as easy as usual,
SecureURL = no
to your pma VirtualHost.
And there you go, it works like a charm!
The „SecureURL“ parameter is not to be found inside the manpages, which I found rather irritating, but well.
