ADVANCED PRODUCT MANAGEMENT UPGRADE
===================================

Before replacing an existing installation, download a backup of:

1. storage/products.json
2. storage/categories.json (if it already exists)
3. storage/brands.json (if it already exists)
4. storage/site.json
5. storage/admin.json
6. storage/enquiries.jsonl
7. the complete assets/uploads folder

Recommended update method:

1. Back up the files listed above.
2. Upload and extract the new package in public_html.
3. Restore your previous site.json, admin.json and enquiries.jsonl.
4. For products from an older version, keep the upgraded products.json supplied by this package or import your existing products through Admin > Import / Export.
5. Restore all existing product uploads into assets/uploads.
6. Set storage and assets/uploads permissions to 775 if your hosting requires it.
7. Log in and open Categories, Brands and Products to verify the data.

New product media folders:

assets/uploads/products/gallery
assets/uploads/products/videos
assets/uploads/products/documents
assets/uploads/brands

For large videos, your hosting PHP settings may need:

upload_max_filesize = 32M or higher
post_max_size = 64M or higher
max_file_uploads = 30 or higher
