I think W3 Total Cache or any Cache related plugin is still activate in your site. Try to de-active all plugins manually. Using Database Open Phpmyadmin Database of the website. In the table wp_options, under the option_name column (field) find the active_plugins row. Change the option_value field to: a:0:{} Using FTP or SSH In case … Read more
All plugins deactivated. What could cause this?
It’s catch 22 – you need WordPress to use the hook system, but init will have already fired during load (wp-settings.php to be exact). I would create a MU “Must Use” plugin (wp-content/mu-plugins/any-filename.php) for all your “outside of WordPress” functionality, with something like this at the start: if ( ! defined( ‘LOADED_EXTERNAL’ ) || ! … Read more
Activation hook is fired while the plugin is being activated, at best it is a dangerous assumption to make that at that point it is already active, and if it is not active, obviously you can not deactivate it. If you are looking for a way to fail the activation, the best way is probably … Read more
The approach in the answer by Scuba Kay is technically possible but easy to get wrong. Small mistakes will cause the data to fail to unserialize correctly. You are better off “editing” the serialized data with PHP: $str=”a:4:{i:0;s:23:”bandpress/bootstrap.php”;i:3;s:56:”posts-from-single-category-widget/post_from_category.php”;i:4;s:15:”something else “;i:5;s:68:”syntax-highlighter-with-add-button-in-editor/syntaxhighlighterpp.php”;}”; // copies from database $strar = unserialize($str); var_dump($strar); // find the key in the var_dump … Read more
You can register multiple activation hooks, that’s not a problem. Or you can use a wrapper function that calls the other functions. What is wrong, is this: add_action( ‘template_include’, ‘terms_redirect’ ); template_include is a filter, not an action, so you should use add_filter(). $author_id = 1; is dangerous, there might be no author with that … Read more
Yes The overhead of a plugin sitting in your plugin folder is negligible, and would have an impact on the plugins page. The main area of optimisation here is the % of free space on your filesystem. Active plugins on the other hand can run queries, make remote requests, do expensive parsing, filesystem operations, and … Read more
I found the solution. First of all, I discover that… you cannot use the admin_notices hook inside the activation hook function. More details here Thanks the link above, I found this solution : class MyAddon { const ACTIVATION_ERROR = “foo-activation-error” public function __construct(){ register_activation_hook( __FILE__, array( $this, ‘install’ ) ); if( is_admin() ){ add_action( “admin_init”, … Read more
Unless you had something installed to track it, then no, that information is lost. WP does not track that information out of the box. Post revisions are the closest thing you will find to an audit log, and those only track changes to posts. You have 2 options to retrieve it: Try to remember which … Read more
You may need to have this line in your code require_once( ABSPATH . ‘wp-admin/includes/plugin.php’ ); The plugin.php file is not automatically included.
