Kinsta’s default PHP memory limit is 256MB, which is more than enough for the majority of WordPress plugins and sites.

If your site is set up correctly at Kinsta, you shouldn’t run into a memory limit error. If you are seeing this error, we recommend checking your WordPress settings to make sure it hasn’t been accidentally set too low.

Checking and Changing Your PHP Memory Limit

To check what your current PHP memory limit is in WordPress, log into your site’s WordPress dashboard and navigate to Tools > Site Health.

Go to the Info tab and click the arrow icon next to the Server section to expand this section and view your PHP memory limit.

If the memory limit is lower than 256M, check your wp-config.php file to see if the WP_MEMORY_LIMIT has been modified and adjust it if needed.

If the memory limit is 256M, but you’re having issues with PHP memory, you can open a new chat with our Support team for help identifying any misconfigured files or other issues.
