Sometimes when attempting to add a WordPress comment, you get a blank page with a single line of error text saying,

“You’re posting comments too quickly. Slow down.”

WordPress has a so-called “flood prevention” input built-in that prevents spam-bots from uploading multiple comments too quickly.

To fix the issue, you need to change a simple function in your .php file. To disable this comment flood function, add this code to your .php:

add_filter('comment_flood_filter', '__return_false');

If you don’t know how to access your functions.php file and add the code, you can use an easier method, which is by using the plugin Code Snippets.

Code Snippets is an easy, clean and simple way to run PHP code snippets on your site. It removes the need to add custom snippets to your theme’s functions.php file.

A snippet is a small chunk of PHP code that you can use to extend the functionality of a WordPress-powered website; essentially a mini-plugin with less load on your site.

Most snippet-hosting sites tell you to add snippet code to your active theme’s functions.php file, which can get rather long and messy after a while.
Code Snippets changes that by providing a GUI interface for adding snippets and actually running them on your site just as if they were in your theme’s functions.php file.

Code Snippets provides graphical interface, similar to the Plugins menu, for managing snippets. Snippets can can be activated and deactivated, just like plugins.

The snippet editor includes fields for a name, a visual editor-enabled description, tags to allow you to categorize snippets, and a full-featured code editor. Snippets can be exported for transfer to another side, either in JSON for later importing by the Code Snippets plugin, or in PHP for creating your own plugin or theme.”

Hope this helps and if you don’t know how to fix that issue using either of those methods, let me know and I’ll gladly help!
