Please try to remove it with the menu slug ‘w3tc_dashboard’ instead of ‘w3tc_general’: i.e. use remove_menu_page( ‘w3tc_dashboard’ ); instead of remove_menu_page( ‘w3tc_general’ ); in the linked code example.
Opcache is transparent for WordPress (as it is to any PHP application). However if you had been using APC for object cache (key/value store) via plugin — that function is not available in new bundled Zend cache, it only does opcode caching. You would need to replace object cache with something different (APCu/Memcache/Redis/etc).
To stop W3 Total Cache from minifying the feeds you need to go to: In the menu: Performance > Minify Meta Box: HTML & XML > HTML minify settings: Check the box for: Don’t minify feeds One of the issues with feed minifying is that it adds CDATA wrapper around javascript in the content and … Read more
Page caching generates a static HTML version of the page so IP geolocation occurs on the first rendering and is not triggered on subsequent renderings – your use case is not compatible with W3 Total Cache’s page caching. It’s possible to accomplish what you are trying to accomplish with page caching, however, you would need … Read more
As @andreascreten, wp-cli will do the job for you. wp-cli includes commands for W3TC (located in the src/php/wp-cli/commands/community/total-cache.php file), so you can flush the cache by running: $ wp total-cache flush <type> Where <type> is one of ‘db’, ‘minify’, ‘object’, ‘page’ or ‘post’. (Note: If you use ‘post’, you’ll need to pass in –post_id= or … Read more
Debug & Caching …simply doesn’t work. If you’d load a page (on a cached request) and doing all those funky things like checking if you’re logged in, if you’re using an administrator-role account, etc. than all this would be bypassed by the caching plugin. The cache gets applied to the resulting HTML page, not the … Read more
You can try to use remove_menu_page(), so you code example would be like: function hide_w3tc() { if (!current_user_can(‘manage_network’)) { remove_menu_page(‘w3tc_dashboard’); } } add_action( ‘admin_menu’, ‘hide_w3tc’,11); where we use a priority greater than the default of 10, since the W3TC menu page is added via add_menu_page(‘Performance’, ‘Performance’, ‘manage_options’, ‘w3tc_dashboard’, ”, ‘div’);
You seem to be a little confused about what function APCu performs. It only implements key/value store. It performs no opcode caching, since the whole point of APCu is to leave that to new Zend implementation of opcode. When you use APC(u) and compatible object cache plugin WP switches to storing its cache (which is … Read more
This is a feature. You can try to disable caching for logged in users, but if it is in the main nav this still won’t help as according to the settings screen: Don’t cache pages for logged in users Unauthenticated users may view a cached version of the last authenticated user’s view of a given … Read more
Have much to say about both W3TC and pagespeed, but will try to stay on the point. You should never have a JS external element in you HTML as part of the actual content, they should be either in the head element (but only scripts that must be loaded before the page finishes loading) or … Read more
