Blank page instead of post

Could you follow the instructions here to enable WP_DEBUG and then refresh the page? Let me know if any errors show up and what they are.

Thank you for your very quick response!
I got two messages:

Notice: register_sidebar_widget is deprecated since version 2.8! Use wp_register_sidebar_widget() instead

Notice: attribute_escape is deprecated since version 2.8! Use esc_attr() instead

Hrm, nothing that relates to CPT UI. Does your site load properly when it’s disabled? Are you able to log into the admin still?

Yes, everything is fine..

And the installation is fine.. the only problem, is when i try to see the custom posts infront, where i get a blank page. All other pages, and posts work normally.

Only my posts https://www.example.com/custom/%example fails and gives me blank screen..

If you know what template file it’s using, could you pastebin that file at pastebin.com?

Also if I could get what settings you used for your CPT, that’d be awesome as well.

the code is

add_action(‘init’, ‘cptui_register_my_cpt’);
function cptui_register_my_cpt() {
register_post_type(‘astheneies’, array(
‘label’ => ‘__(‘Ασθ?νειε?’)’,
‘description’ => ”,
‘public’ => ‘true’,
‘show_ui’ => ‘true’,
‘show_in_menu’ => ‘true’,
‘capability_type’ => ‘post’,
‘hierarchical’ => ‘false’,
‘rewrite’ => array(‘slug’ => ‘astheneies’, ‘with_front’ => ‘1’),
‘query_var’ => ‘true’,
‘has_archive\’ => ‘true’,
‘exclude_from_search’ => ‘false’,
‘supports’ => array(”title’,’editor’,’excerpt’,’trackbacks’,’custom-fields’,’comments’,’revisions’,’thumbnail’,’author’,’page-attributes’,’post-formats’,’),
‘labels’ => ‘array (
‘name’ => ‘Ασθ?νειε?’,
‘singular_name’ => ‘Ασθ?νεια’,
‘menu_name’ => ‘Ασθ?νειε?’,
‘add_new’ => ‘Προσθ?κη ν?α?’,
‘add_new_item’ => ‘Προσθ?κη ν?α? ασθ?νεια?’,
‘edit’ => ‘Επεξεργασ?α’,
‘edit_item’ => ‘Επεξεργασ?α ασθ?νεια?’,
‘new_item’ => ‘Ν?α ασθ?νεια’,
‘view’ => ‘Προβολ?’,
‘view_item’ => ‘Προβολ? ασθ?νεια?’,
‘search_items’ => ‘Αναζ?τηση ασθ?νεια?’,
‘not_found’ => ‘Δεν βρ?θηκαν ασθ?νειε?’,
‘not_found_in_trash’ => ‘Δεν βρ?θηκαν ασθ?νειε? στα απορρ?μματα’,
‘parent’ => ‘Γονικ? ασθ?νεια’,
)’
) ); }

how can i find which theme file is using?

I havent edited any other file, except from functions.php, where i inserted the code above.. ??

The generated code of your plugin version has errors, e.g.
'supports' => array(''title','editor','excerpt','trackbacks','custom-fields','comments','revisions','thumbnail','author','page-attributes','post-formats','),
should be
'supports' => array('title','editor','excerpt','trackbacks','custom-fields','comments','revisions','thumbnail','author','page-attributes','post-formats'),
etc.

In general, if you have Custom Post Type UI installed and active, do NOT copy the code to your functions.php, the register_post_type() is done by the plugin itself.

And the Get Code is hopefully fixed in 8.1 which I am waiting on a bit of testing + permission to release. Ov3rfly is right though, the Get Code bit doesn’t handle the registering when the plugin is active.

It should be stable enough that I am fine with doing this. Evoweb, download this here: https://github.com/WebDevStudios/custom-post-type-ui/archive/master.zip

and extract the contents into the same plugin folder on your server. Keep the folder name the same though. Once things get pushed out to WP.org, if there’s anything different, you should get a prompt to update it via your admin later, and you’ll still get the latest version.
