I decided that i prefer to use Tags in this blog rather than Categories… so i converted all the existing Categories to Tags and went to disable Categories. Only i can’t find anywhere in the WordPress settings to turn off all reference to them and thus all my posts were left reading “Posted in Uncategorized …” under the title. Messy.
Fortunately WordPress’ inbuilt editor means you can simply edit out bits you don’t want, so i was able to just delete (well, comment-out) all references to “the_category” i found in the Simplex theme. If you want to so the same you’ll need to fiddle with index.php, single.php, archive.php and search.php.
