This is a bug (one that I’ve encountered before) and could do with a ticket in trac (since I never took the time to submit one!) The trouble starts with requests that set multiple is_* query flags as true (specifically flags that represent objects, such as single posts, pages, and post type & term archives). … Read more
There is a section that should look like this: defined( ‘ABSPATH’ ) || define( ‘ABSPATH’, __DIR__ . “https://wordpress.stackexchange.com/” ); require_once( ABSPATH . ‘wp-settings.php’ ); add_filter() is available after that, you are probably using it too early.
Since version 3.4 (or earlier?) WordPress sends a special HTTP header (not in HTML) on login and admin pages: X-Frame-Options: SAMEORIGIN So your browser will show you some text built into the browser, not sent from WordPress. From wp-includes/default-filters.php: add_action( ‘login_init’, ‘send_frame_options_header’, 10, 0 ); add_action( ‘admin_init’, ‘send_frame_options_header’, 10, 0 ); You could create a … Read more

Add the following at the top of wp-config.php: ini_set(‘memory_limit’,’128M’); Although you should use WP_MEMORY_LIMIT when you can, we see in /wp-includes/default-constants.php that WordPress doesn’t do much more than use ini_set itself. Note: This is just one more thing to try, but you’ll likely end up having to have your host fix this issue.
Your exception isn’t caught by the try{} catch(){} block, because it isn’t thrown inside the try catch block. This demonstrates a lack of understanding of asynchronous events and the WordPress hook/action/event system. The methods of your object are attached to the init action hook, and are thrown when the init hook is fired, not when … Read more
