svn - websvn is not ignoring mime type -

I am using websvn to see the comparison of svn modifications i uncommented my config.php To do $ config- & gt; IgnoreSvnMimeTypes ();
, but it does not look like:

can not be displayed: the file has been marked as binary type.
svn: mime-type = application / octet-stream

What am I missing?

My workspace mime type

was to change
