WordPress Defined Memory Limit
Try one (or more) of the below methods to increase the memory allicated by PHP. First try increasing the limit to 64MB, and if that fails use 96M. You can define the WP_MEMORY_LIMIT constant in wp-config.php: Increase PHP Memory to 64MB define(‘WP_MEMORY_LIMIT’, ’64M’); Increase PHP Memory to 96MB define(‘WP_MEMORY_LIMIT’, ’96M’); You can also change the … Read more
Make WP_Query more efficient?
you can try some of these extra parameters: ‘update_post_term_cache’ => false, ‘update_post_meta_cache’ => false, ‘cache_results’=>false, ‘no_found_rows’ => true, ‘posts_per_page’=>1, ‘post_status’=’publish’, ps: you can measure the speed of your query when you are testing it with microtime() http://php.net/manual/en/function.microtime.php Edit: Here is a another way: function count_votes($user_id=1, $question_id=1, $post_type=”vote”, $meta_key=’comp_question’){ global $wpdb; $sql = “SELECT count(*) FROM … Read more
Downsize CPU & DB usage in wordpress
Sagive, wp-blog-header.php loaded in the index.php on each page request. AJAX calls included (if that’s what you mean “time after time”. Then it loads template-loader.php. This has nothing to do with the SQLs you see, and not with the “spikes”. Install the Query Monitor plugin to see your SQLs better in the Debug Bar. Do … Read more
Updating beyond WordPress 4.2.1 yields “allowed memory size exhausted”
Edit line 149 in file.php as described in this thread: https://wordpress.org/support/topic/unable-to-update-plugins-after-upgrade-to-42 fixed it for me (on a linux host). edit: just read you are on windows: someone also posted a fix that applies to windows hosts there (apparently more complicated because backslashes are used in filepaths). so your line 149 in file.php should read: if … Read more
WordPress out of memory allocated issue?
If you are on any environment you did not personally set up, you may not have the permissions to override the php.ini file. Also some plugins can manually do: ini_set( ‘memory_limit’, ‘512M’);
Set WP_MAX_MEMORY_LIMIT higher than PHP.ini memory_limit
The true maximum is ultimately up to the host – they can impose whatever limits they wish. But even so, you can try with WP_MEMORY_LIMIT, which is the memory limit WordPress sets at runtime for any given request. WP_MAX_MEMORY_LIMIT is only applied in certain situations, either for administrators in the backend (users with the capability … Read more
Are there individual memory allocations for different user roles in WordPress?
Because of this line in wp-admin/admin.php: if ( current_user_can( ‘manage_options’ ) ) { wp_raise_memory_limit( ‘admin’ ); } In other words, WordPress raises the memory limit to WP_MAX_MEMORY_LIMIT within the admin, but only for users with the manage_options capability i.e. administrators. Your best bet is to raise the default memory limit in your wp-config.php: define( ‘WP_MEMORY_LIMIT’, … Read more
Can you limit the memory usage of a particular plugin?
No and even if you could, if the plugin ran out of available memory then the entire page generation would stop due to the fatal error. You’re better off fixing the plugin itself to not use as much memory or to just further increase the total memory allocated to WordPress/PHP.
Memory errors with media upload, WordPress can’t use more than 96M (while there’s 512 available!)
You’re looking at the problem the wrong way. The error you’re seeing isn’t an error coming from WordPress, it’s a PHP error. Somehow, somewhere, something is limiting the memory limit to 96M, and it ain’t WordPress that’s doing it. Here’s the thing: WordPress can’t actually limit the memory on most servers. I know that it … Read more
