page-{slug}.php vs. template-{slug}.php
So my question is, should I assume that this is a theme-based functionality, where some themes provide support for files with the template-{slug}.php naming? Correct. Or do all WordPress applications allow for such files? If so, where can I find instructions on how to use template-{slug}.php files? Or is there another way these days to … Read more
Best practice to update the file header.php
This question leans towards getting some subjective answers, as I think it’s a matter of personal preference. The built-in editor works just as well as any other text editor.

So in your registration code use: ‘has_archive’ => ‘jobs’ From the register_post_type() declaration in WordPress core: if ( $args->has_archive ) { $archive_slug = $args->has_archive === true ? $args->rewrite[‘slug’] : $args->has_archive; if ( $args->rewrite[‘with_front’] ) $archive_slug = substr( $wp_rewrite->front, 1 ) … Read more
URL / Templating system advice [closed]
Do you have: A category somecategory defined? Posts categorized with somecategory? Some default else: content in the Loop in category.php? I suspect the URL is returning a 404, and WordPress is simply serving up the root URL, because it has no content to serve up from category.php. EDIT You don’t need to do anything special … Read more
Where is Number of Posts Set?
That looks like a http://para.llel.us/support/ theme. You might start there for docs—for instance, they probably have a custom ‘Theme Options’ page in the admin.
