Technical & Storage Prerequisites

Writable Media Directory:
The extension saves uploaded body measurement diagrams under pub/media/mpsizecharttemplate/. Ensure the web server user (www-data, nginx, or apache) has read/write permissions:
```
chmod -R 775 pub/media
```
Database Support for JSON Column:
The module stores size chart template matrices in a native json column (chart_info) in the wk_mpsizechart_templates table. Ensure your MySQL/MariaDB version supports JSON data types (MySQL 5.7.8+ or MariaDB 10.2.7+).
JavaScript Enabled:
The interactive size chart popup uses jQuery UI modals, Knockout.js templates, and dynamic event handlers. JavaScript must be enabled in client browsers.
Product Types:
The size chart template dropdown attribute is scoped and applied to Simple and Configurable product types.
