Found a way. Create a regular page for 404 content, say ‘Page not found’; In your 404.php file, get that page data and then write down your content or whatever… For example: $page = get_page_by_title(“Page not found”); if($page) echo apply_filters(‘the_content’,$page->post_content); Obviously, you can do a lot more…
Removing ‘query_var’=> false solved this. Thanks to @PedroCoitinho
While you’ve found the problem already, here is some basic code to move a specific rule to the end of the rewrite rules with the rewrite_rules_array filter for people stumbling across a similar problem. Say I want to move the rule for ([^/]*)/([^/]*)/?$: add_filter(“rewrite_rules_array”, function($rules) { $keys = array_keys($rules); foreach($keys as $rule) { if($rule == … Read more
TL:DR: The slug of the home page and a folder at the root had the same name There was a folder that I was using for home page assets, the address was “example.net/home/” and the original WP development was “example.net/wordpress/”. When I moved the wordpress files out to the root, the home page had a … Read more
I’ve had this issue on a small number of sites (out of around 60 that I help manage), and I’m wondering if the issue is caused by caching (by a plugin or theme). If you have a caching plugin, or a theme that does caching, there should be a tool in the Dashboard for emptying/clearing/deleting … Read more
After trying a million of ways, I contacted the super admin and asked for permission to log into WP Engine, our host. I found there is a Multisite setting too. So I clicked “convert to multisite”, and, bang! the error is resolved. Subsites can work properly now.
If you’re running WordPress 3.0.1 or later, I believe your problem lies with the ‘post_type_link’ filter declaration and function arguments. When the ‘post_type_link’ filter is applied, it passes the following 4 arguments: apply_filters(‘post_type_link’, $post_link, $post, $leavename, $sample); But your function accepts $post_link and $id. Try the following adjustments: function custom_post_link( $post_link, $post ) { if … Read more
If you intend to do checks based on template tags you should hook on wp action. template_redirect will suffice too, but wp is earlier. This is when WP handles 404 itself. To perform a 301 redirect use status_header( 301 );, wp_safe_redirect(); immediately followed by exit; You could use a plugin handle these for you. It’s … Read more
Two options: Use conditional code inside of 404.php, to output different content/markup for the post-type Intercept the template at template_redirect, and include a separate template file for a 404 for the post-type. Personally, I’d go with option 1, as it is easier and more intuitive.
The no no about loading wp-* files directly are reasonable when you are developing a WordPress plugin or theme, but if you are developing an external code that require WP (and that seems your case) than you must require that files, there is no alternatives. Consider that including wp-blog-header.php is needed when you need to … Read more
