Another (quick to test) hunch: Under WPSC “Advanced” settings: check on “Simple” then check the “Late Init” (and/or “HTTP Headers”) boxes – save settings.

It appears that you’re trying to get the latest 15 posts where the meta key is not equal to ‘None’. Instead of loading all the posts into memory and then looping through to see if the meta value is not ‘None’, you could use the meta_query parameter. $args = [ ‘post_type’ => ‘post’, ‘orderby’ => … Read more
This is because of your plugin code is executed much earlier, than wp-login.php. You can read about WordPress loading sequence here, for example. To behave properly, your code must be executed in ‘wp_login’ hook: add_action( ‘wp_login’, ‘wp_login_action’, 10, 2 ); function wp_login_action( $user_login, $user ) { current_user = wp_get_current_user(); print_r($current_user); }
When a plugin is updated, its folder gets deleted and recreated with the updated version. This would destroy any caches, which on a heavily trafficked site could bring down the server Additionally, the plugins folder on a lot of servers is read only to the user the web server runs as for security reasons. It … Read more

It helps to reduce unnecessary load. location ~* \.(?:ico|css|js|gif|jpe?g|png)$ { expires 30d; add_header Pragma public; add_header Cache-Control “public”; }
Please, enable the debug mode in WordPress maybe there will be answer. To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to: ‘define(‘WP_DEBUG’, true);’ In order to enable the error logging to a file on the server you need to add yet one more similar line: ‘define( ‘WP_DEBUG_LOG’, true );’ … Read more
The option_value column in the database is LONGTEXT, meaning it can hold up to 4GB of text. But keep in mind that WordPress loads all options on every page load by default, and storing large values for options you only intend to use on a single page is inefficient.
