Fixing the "Memory Limit Exceeded" PHP Error

This error means a PHP script tried to use more memory than it's allowed, and the server stopped it to protect overall stability.

Common Causes

A plugin processing a large image, an import handling too much data at once, or simply a memory limit set too low for your site's actual needs.

Increasing the Limit

In Plesk's PHP settings, increase the memory_limit value — a modest bump (like from 128M to 256M) resolves most cases.

Addressing the Root Cause

If the error keeps recurring even after increasing the limit, a specific plugin or piece of code is likely inefficient — worth investigating rather than repeatedly raising the ceiling.
