The link here is ?p=1448&preview=true
Which should be redirected to the /index.php
If I press that link it goes to:
/?p=1429&preview_id=1429&preview_nonce=ddfbdb8ba3&_thumbnail_id=1430&preview=true
Which shows: Sorry, you are not allowed to preview drafts
I could find the message in \wp-content\languages\it_IT.po
#: wp-includes/revision.php:550
msgid "Sorry, you are not allowed to preview drafts."
msgstr "Non hai i permessi per visualizzare le bozze in anteprima."
Looking for the I've reached this method
/wp-includes/revision.php.html
/**
539 * Filters the latest content for preview from the post autosave.
540 *
541 * @since 2.7.0
542 * @access private
543 */
544 function _show_post_preview() {
545 if ( isset($_GET['preview_id']) && isset($_GET['preview_nonce']) ) {
546 $id = (int) $_GET['preview_id'];
547
548 if ( false === wp_verify_nonce( $_GET['preview_nonce'], 'post_preview_' . $id ) )
549 wp_die( __('Sorry, you are not allowed to preview drafts.') );
550
551 add_filter('the_preview', '_set_preview');
552 }
553 }
Enabling define('WP_DEBUG', true) in the config file only shows a deprecated error message.
Cloudflare is disabled, flushing the local cache has no impact.
Disabling the check I get this error:
Oops! That page can not be found.
What can I try more?
