# Coriable public-page reliability fix

This release fixes the reported 404 and HTTP 500 errors for Solutions and Industries.

## Root causes addressed

1. The industry detail template queried `slug`, `content_json` and SEO fields that do not exist in the original `industries` table. On installations where the optional SQL migration failed or was not imported, PDO threw an exception and returned HTTP 500.
2. Several priority Solution pages depended entirely on database records created by a later migration. Missing or partially imported records produced 404 errors.
3. Some MySQL/MariaDB versions used by shared hosting do not support all `ALTER TABLE ... IF NOT EXISTS` forms contained in the previous optional content migration.

## New behaviour

- The nine priority Solution pages are included in a built-in content catalogue and work even before a database migration.
- Existing database content still overrides or extends built-in content when available.
- All industry pages have built-in content and clean `/industries/<slug>` URLs.
- Industry detail pages remain compatible with the original six-column `industries` table.
- Public templates catch incomplete-migration database errors instead of exposing HTTP 500.
- Content spacing, cards, sidebars, hero buttons and mobile layout have been revised.

## Required deployment

Upload all files, including `.htaccess`, `includes/solution-catalog.php`, `service-single.php`, `industries.php`, `industry-single.php`, and `css/custom.css`.

Purge the Cloudflare cache and test in an incognito window. No database import is required for the priority pages in this release.
