In my case, it was simply the SITE URL left blank in Settings -> General. I filled it with my site URL, and everything started working again. I found out by enabling WP_DEBUG in wp-config.php, and I got this error: “Notice: Undefined index: host”
WP_DEBUG has no impact on PHP error output. In addition to error_reporting setting, set display_errors=0 in your php.ini file. It’s enabled by default for development. But you’ll want it off on production servers.
WordPress 5.3 introduces a considerably simpler way to achieve this. By registering theme support for HTML 5 for script and style, the type=”” attribute will be omitted: add_action( ‘after_setup_theme’, function() { add_theme_support( ‘html5’, [ ‘script’, ‘style’ ] ); } );
you can do that using login_errors filter hook and here is how: add_filter(‘login_errors’,’login_error_message’); function login_error_message($error){ //check if that’s the error you are looking for $pos = strpos($error, ‘incorrect’); if (is_int($pos)) { //its the right error so you can overwrite it $error = “Wrong information”; } return $error; } update: i just tested the code and … Read more

I would recommend running the following code right after your query to see what’s happening: exit( var_dump( $wpdb->last_query ) ); This should print the last query that hit your database. In cases like these, I usually will manually run such a query through phpMyAdmin to see if it runs without errors and to see if … Read more
Disable all plugins and switch to the default theme. It should be gone now. Then enable each addon step by step, until the problem comes back. You know the source now, let’s say a plugin. The plugin calls probably wp_enqueue_script too early. Find all occurrences of that function, then make sure they are bound to … Read more
Store errors in your class or as a global, possibly in a transient or meta, and display them in admin notices on POST requests. WP does not feature any flash message handler.
I’m assuming that you put WordPress in your site root and the external directories are also in your site root. The reason this is happening is that .htaccess files follow a hierarchy. Whatever directives are in the top-level .htaccess file flow down and apply to all directories below it. If this is the case, you … Read more
