WordPress is an incredibly popular platform for creating and managing websites, with over 40% of the internet powered by WordPress. However, like any software, it has its limitations. One of those limitations is the PHP memory limit. In this article, we’ll explain that how to fix or increase PHP memory limit in WordPress.
What is the PHP Memory Limit?
The PHP memory limit is the maximum amount of memory that PHP scripts can use while running on a server. PHP is a scripting language that WordPress uses to generate dynamic content on a website. When a PHP script runs, it needs to allocate memory to store variables, objects, and other data. If your WordPress website is running large scripts or has a lot of images on the post, you may encounter the following error message while editing the post:
- Fatal error: Allowed memory size of 134217728 bytes exhausted.

You may also encounter fatal error on wordpress site or “there has been a critical error on your website in wordpress“.
Why is the PHP Memory Limit Important?
The PHP memory limit is important because it can affect the performance and stability of your WordPress website. If your PHP scripts are using too much memory, your server may slow down, or your website may crash. Increasing the PHP memory limit can help to prevent these issues and improve the performance of your website.
