Every aspect of my dashboard is slow--it can take 30-60 seconds to get a list of pages, or to updated a post. Yet, the front end is fast.

I checked all the plugins--no problem there. I deactivated all the features of JetPack--no problem there.

I tried different browsers--no problem there.

I checked with my ISP and they confirmed there was no down time.

This problem is ongoing.

What makes WordPress dashboard slow and how do I fix it?

Try this link: Wordpress Support

It suggests these 7 steps about half way down:

  1. Manually run /wp-admin/upgrade.php (visit it in your browser).

  2. Try decativating all plugins. If that resolves the issue, reactivate each one individually until you find the cause.

  3. Try switching to the Twenty Ten theme to rule-out a theme-specific issue.

  4. Download WordPress again and delete then replace your copies of the /wp-admin/ and /wp-includes/ directories with fresh copies from the download.

  5. Access your WordPress database via phpMyAdmin (most hosting providers offer this in their control panel), check all of the tables, and choose "Optimize tables" from the pull-down menu.

  6. Try installing the Memory Bump plugin.

  7. If nothing else works, try these methods to increase PHP's memory allocation:

    1. If you have access to your PHP.ini file, change the line in PHP.ini If your line shows 32M try 64M: memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)

    2. If you don't have access to PHP.ini try adding this to an .htaccess file: php_value memory_limit 64M

    3. Try adding this line to your wp-config.php file: Increasing memory allocated to PHP define('WP_MEMORY_LIMIT', '64M');

    4. Talk to your host.

    /wp-admin/upgrade.php was the solution - I'm running multisite, so I had to do it on all the subsites (subdomain based) and it fixed the problem. Jan 17, 2014 at 9:19
  • Thank you, unfrev....You saved my day....My WordPress MU dashboard pages were barely working after an upgrade to 4.3.1, until I ran wp-admin/upgrade.php in the browser! Nov 17, 2015 at 16:42
