We need an experienced PHP/Apache expert to fix an issue with a very old image upload system. Background We are running an old script: since 2011 Uploaderv6.3.5.0 © celerondude.com The developer no longer exists. The system has been working perfectly for more than 15 years. We have: 3,6 GB images uploaded major revenue impact because images are missing What happened Our hosting provider migrated us to a new server. Since the migration: OLD images → return "File not found" (404) NEW uploads → work perfectly Example admin: https://hochspannungsmotoren.com/ebay/browse/admin Important The image files SHOULD still exist on the server.
