wp_mail() is defined in wp-includes/pluggable.php. This file is loaded after the plugins are loaded, but before the hook plugins_loaded has been fired. So the answer is: wait. add_action( ‘plugins_loaded’, ‘renderHTML’ ); On a side note: prefix your function names and your global variables.
As a rule of thumb, always remove the ending ?> of your .php files, especially if it’s a functions or config file that gets parsed before headers are sent to the page. If after that ?> you accidentally add a space, a tab character or a new line, there’s your invisible error.
To get WordPress to display errors, edit the wp-config.php file to say define( ‘WP_DEBUG’, true ); By default, this is set to false and should be towards the bottom of the file. That will allow you to see which errors are being produced. Also, whitespace at the end of files almost never causes the WSOD; … Read more
There were wp files in the web root which had file size of 0 bytes. Uploading proper copies from the zip file resolved the problem. The same cause of the problem has occurred to me quite a few times in the past, but I had forgotten it.
You are missing a table. You can add it using this sql CREATE TABLE `wp_termmeta` ( `meta_id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `term_id` bigint(20) unsigned NOT NULL DEFAULT ‘0’, `meta_key` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL, `meta_value` longtext COLLATE utf8mb4_unicode_ci, PRIMARY KEY (`meta_id`), KEY `term_id` (`term_id`), KEY `meta_key` (`meta_key`(191)) ) ENGINE=InnoDB AUTO_INCREMENT=3255 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
You have found a bug in Genesis. Your Xdebug stack trace fingers the culprit as the genesis_save_custom_fields() function which calls current_user_can() with a singular capability (edit_post and edit_page) which also requires an additional argument, in this case the post ID which is missing. current_user_can() calls has_cap() which calls map_meta_cap() which does a switch statement on … Read more
This is to extend your own answer: It appears that when “hierarchical” is set to true, each post behaves like a page. I am quoting here so I don’t really understand why it matters but changing this line remove the problem. Here is what the codex says about the hierarchical parameter hierarchical (boolean) (optional) Whether … Read more
wp() is quite essential function. It resides in functions.php file (don’t confuse with functions.php in theme, different thing) and I don’t think you can load WP without passing require directive for that file at some point. So your install seems very broken – either functions.php file in core is damaged or something else is broken … Read more
I fixed this by going through PHPMyAdmin to the table “Options” and then the row active_plugins. I had the following stored there (formatted for readability): a:10:{ i:0;s:49:”1and1-wordpress-wizard/1and1-wordpress-wizard.php”; i:1;s:29:”acf-repeater/acf-repeater.php”; i:2;s:30:”advanced-custom-fields/acf.php”; i:3;s:45:”limit-login-attempts/limit-login-attempts.php”; i:4;s:27:”redirection/redirection.php”; i:6;s:33:”w3-total-cache/w3-total-cache.php”; i:7;s:41:”wordpress-importer/wordpress-importer.php”; i:8;s:24:”wordpress-seo/wp-seo.php”; i:9;s:34:”wpml-string-translation/plugin.php”; i:10;s:38:”wpml-translation-management/plugin.php”; } I added a new line (for the missing plugin) and incremented the a:10 to a:11 to indicate that … Read more
