The PHP memory_limit value helps you manage the memory usage within PHP scripts. It specifies the maximum amount of memory that a PHP script is allowed to allocate during its execution. This limit serves as a safeguard against scripts consuming excessive memory, which can lead to performance issues and potentially crash the server..
Check your PHP memory limit
All of our Web and Cloud hosting plans come with fixed maximum memory_limit values. To check the value corresponding to your hosting plan, go to the PHP Info page on your hPanel and search for memory_limit:

NOTE
- If your website is built with WordPress, it may use a lower default memory_limit. See how to increase the WordPress memory limit, or how to change the WordPress upload limitation at Hostinger if the issue relates specifically to uploads.
Change or increase your limit
To adjust the value directly, see how to change values of PHP parameters in Hostinger.
If your project has grown and you need to increase the overall memory limit, you can consider upgrading your hosting plan.
